Cloud config examples#

Including users and groups#

  1#cloud-config
  2# Add groups to the system
  3# The following example adds the 'admingroup' group with members 'root' and 'sys'
  4# and the empty group cloud-users.
  5groups:
  6  - admingroup: [root,sys]
  7  - cloud-users
  8
  9# Add users to the system. Users are added after groups are added.
 10# Note: Most of these configuration options will not be honored if the user
 11#       already exists. Following options are the exceptions and they are
 12#       applicable on already-existing users:
 13#       - 'plain_text_passwd', 'hashed_passwd', 'lock_passwd', 'sudo',
 14#         'ssh_authorized_keys', 'ssh_redirect_user'.

 50
 51# Valid Values:
 52#   name: The user's login name
 53#   expiredate: Date on which the user's account will be disabled.
 54#   gecos: The user name's real name, i.e. "Bob B. Smith"
 55#   homedir: Optional. Set to the local path you want to use. Defaults to
 56#           /home/<username>
 57#   primary_group: define the primary group. Defaults to a new group created
 58#           named after the user.
 59#   groups:  Optional. Additional groups to add the user to. Defaults to none
 60#   selinux_user:  Optional. The SELinux user for the user's login, such as
 61#           "staff_u". When this is omitted the system will select the default
 62#           SELinux user.
 63#   lock_passwd: Defaults to true. Lock the password to disable password login
 64#   inactive: Number of days after password expires until account is disabled
 65#   passwd: The hash -- not the password itself -- of the password you want
 66#           to use for this user. You can generate a hash via:
 67#               mkpasswd --method=SHA-512 --rounds=4096
 68#           (the above command would create from stdin an SHA-512 password hash
 69#           with 4096 salt rounds)
 70#
 71#           Please note: while the use of a hashed password is better than
 72#               plain text, the use of this feature is not ideal. Also,
 73#               using a high number of salting rounds will help, but it should
 74#               not be relied upon.
 75#
 76#               To highlight this risk, running John the Ripper against the
 77#               example hash above, with a readily available wordlist, revealed
 78#               the true password in 12 seconds on a i7-2620QM.
 79#
 80#               In other words, this feature is a potential security risk and is
 81#               provided for your convenience only. If you do not fully trust the
 82#               medium over which your cloud-config will be transmitted, then you
 83#               should not use this feature.
 84#
 85#   no_create_home: When set to true, do not create home directory.
 86#   no_user_group: When set to true, do not create a group named after the user.
 87#   no_log_init: When set to true, do not initialize lastlog and faillog database.
 88#   ssh_import_id: Optional. Import SSH ids
 89#   ssh_authorized_keys: Optional. [list] Add keys to user's authorized keys file
 90#                        An error will be raised if no_create_home or system is
 91#                        also set.
 92#   ssh_redirect_user: Optional. [bool] Set true to block ssh logins for cloud
 93#       ssh public keys and emit a message redirecting logins to
 94#       use <default_username> instead. This option only disables cloud
 95#       provided public-keys. An error will be raised if ssh_authorized_keys
 96#       or ssh_import_id is provided for the same user.
 97#
 98#   sudo: Defaults to none. Accepts a sudo rule string, a list of sudo rule
 99#         strings or False to explicitly deny sudo usage. Examples:
100#
101#         Allow a user unrestricted sudo access.
102#             sudo:  ALL=(ALL) NOPASSWD:ALL
103#
104#         Adding multiple sudo rule strings.
105#             sudo:
106#               - ALL=(ALL) NOPASSWD:/bin/mysql
107#               - ALL=(ALL) ALL
108#
109#         Prevent sudo access for a user.
110#             sudo: False
111#
112#         Note: Please double check your syntax and make sure it is valid.
113#               cloud-init does not parse/check the syntax of the sudo
114#               directive.
115#   system: Create the user as a system user. This means no home directory.
116#   snapuser: Create a Snappy (Ubuntu-Core) user via the snap create-user
117#             command available on Ubuntu systems.  If the user has an account
118#             on the Ubuntu SSO, specifying the email will allow snap to
119#             request a username and any public ssh keys and will import
120#             these into the system with username specified by SSO account.
121#             If 'username' is not set in SSO, then username will be the
122#             shortname before the email domain.
123#
124
125# Default user creation:
126#
127# Unless you define users, you will get a 'ubuntu' user on Ubuntu systems with the
128# legacy permission (no password sudo, locked user, etc). If however, you want
129# to have the 'ubuntu' user in addition to other users, you need to instruct
130# cloud-init that you also want the default user. To do this use the following
131# syntax:
132#   users:
133#     - default
134#     - bob
135#     - ....
136#  foobar: ...
137#
138# users[0] (the first user in users) overrides the user directive.
139#
140# The 'default' user above references the distro's config:
141# system_info:
142#   default_user:
143#     name: Ubuntu
144#     plain_text_passwd: 'ubuntu'
145#     home: /home/ubuntu
146#     shell: /bin/bash
147#     lock_passwd: True
148#     gecos: Ubuntu
149#     groups: [adm, audio, cdrom, dialout, floppy, video, plugdev, dip, netdev]

Adding a yum repository#

 1#cloud-config
 2# vim: syntax=yaml
 3#
 4# Add yum repository configuration to the system

 7# which can then subsequently be used by yum for later operations.
 8yum_repos:
 9  # The name of the repository
10  epel-testing:

16  remove_defaults: true
17
18  # If present, the 'trusted' parameter should contain a certificate (or list

 6# Additional apt configuration and repositories section.
 7#
 8#
 9# Default: auto select based on cloud metadata
10#  in ec2, the default is <region>.archive.ubuntu.com

14#       uri:
15#     use the provided mirror
16#       search:
17#     search the list for the first mirror.
18#     this is currently very limited, only verifying that
19#     the mirror is dns resolvable or an IP address
20#
21# if neither mirror is set (the default)
22# then use the mirror provided by the DataSource found.
23# In EC2, that means using <region>.ec2.archive.ubuntu.com
24#
25# if no mirror is provided by the DataSource, but 'search_dns' is
26# true, then search for dns names '<distro>-mirror' in each of
27# - fqdn of this host per cloud metadata
28# - localdomain
29# - no domain (which would search domains listed in /etc/resolv.conf)
30# If there is a dns entry for <distro>-mirror, then it is assumed that there
31# is a distro mirror at http://<distro>-mirror.<domain>/<distro>
32#
33# That gives the cloud provider the opportunity to set mirrors of a distro
34# up and expose them only by creating dns entries.
35#
36# if none of that is found, then the default distro mirror is used

Run commands on first boot#

 1#cloud-config

 3# boot commands
 4# default: none
 5# this is very similar to runcmd, but commands run very early
 6# in the boot process, only slightly after a 'boothook' would run.
 7# bootcmd should really only be used for things that could not be
 8# done later in the boot process.  bootcmd is very much like
 9# boothook, but possibly with more friendly.
10# - bootcmd will run on every boot
11# - the INSTANCE_ID variable will be set to the current instance id.
12# - you can use 'cloud-init-per' command to help only run once
13bootcmd:
14  - echo 192.168.1.130 us.archive.ubuntu.com >> /etc/hosts
15  - [ cloud-init-per, once, mymkfs, mkfs, /dev/vdb ]

 3# run commands
 4# default: none
 5# runcmd contains a list of either lists or a string
 6# each item will be executed in order at rc.local like level with
 7# output to the console
 8# - runcmd only runs during the first boot
 9# - if the item is a list, the items will be properly executed as if
10#   passed to execve(3) (with the first arg as the command).
11# - if the item is a string, it will be simply written to the file and
12#   will be interpreted by 'sh'
13#
14# Note, that the list has to be proper yaml, so you have to quote
15# any characters yaml would eat (':' can be problematic)
16runcmd:
17 - [ ls, -l, / ]
18 - [ sh, -xc, "echo $(date) ': hello world!'" ]

 71  # modifications have been made.
 72  # Suites are even disabled if no other modification was made,
 73  # but not if is preserve_sources_list is active.
 74  # There is a special alias "$RELEASE" as in the sources that will be replace

 75# "disk_setup": disk partitioning
 76# --------------------------------
 77
 78# The disk_setup directive instructs Cloud-init to partition a disk. The format is:
 79
 80disk_setup:
 81  ephemeral0:
 82    table_type: 'mbr'
 83    layout: true
 84  /dev/xvdh:
 85    table_type: 'mbr'
 86    layout:
 87      - 33
 88      - [33, 82]
 89      - 33
 90    overwrite: True
 91
 92# The format is a list of dicts of dicts. The first value is the name of the
 93# device and the subsequent values define how to create and layout the
 94# partition.
 95# The general format is:
 96#   disk_setup:
 97#     <DEVICE>:
 98#       table_type: 'mbr'
 99#       layout: <LAYOUT|BOOL>
100#       overwrite: <BOOL>
101#
102# Where:
103#   <DEVICE>: The name of the device. 'ephemeralX' and 'swap' are special
104#               values which are specific to the cloud. For these devices
105#               Cloud-init will look up what the real devices is and then
106#               use it.
107#
108#               For other devices, the kernel device name is used. At this
109#               time only simply kernel devices are supported, meaning
110#               that device mapper and other targets may not work.
111#
112#               Note: At this time, there is no handling or setup of
113#               device mapper targets.
114#
115#   table_type=<TYPE>: Currently the following are supported:
116#                   'mbr': default and setups a MS-DOS partition table
117#                   'gpt': setups a GPT partition table
118#
119#               Note: At this time only 'mbr' and 'gpt' partition tables
120#                   are allowed. It is anticipated in the future that
121#                   we'll also have "RAID" to create a mdadm RAID.
122#
123#   layout={...}: The device layout. This is a list of values, with the
124#               percentage of disk that partition will take.
125#               Valid options are:
126#                   [<SIZE>, [<SIZE>, <PART_TYPE]]
127#
128#               Where <SIZE> is the _percentage_ of the disk to use, while
129#               <PART_TYPE> is the numerical value of the partition type.
130#
131#               The following setups two partitions, with the first
132#               partition having a swap label, taking 1/3 of the disk space
133#               and the remainder being used as the second partition.
134#                 /dev/xvdh':
135#                   table_type: 'mbr'
136#                   layout:
137#                     - [33,82]
138#                     - 66
139#                   overwrite: True
140#
141#               When layout is "true" it means single partition the entire
142#               device.
143#
144#               When layout is "false" it means don't partition or ignore
145#               existing partitioning.
146#
147#               If layout is set to "true" and overwrite is set to "false",
148#               it will skip partitioning the device without a failure.
149#
150#   overwrite=<BOOL>: This describes whether to ride with safetys on and
151#               everything holstered.
152#
153#               'false' is the default, which means that:
154#                   1. The device will be checked for a partition table
155#                   2. The device will be checked for a filesystem
156#                   3. If either a partition of filesystem is found, then
157#                       the operation will be _skipped_.
158#
159#               'true' is cowboy mode. There are no checks and things are
160#                   done blindly. USE with caution, you can do things you
161#                   really, really don't want to do.
162#
163#
164# fs_setup: Setup the filesystem
165# ------------------------------
166#
167# fs_setup describes the how the filesystems are supposed to look.
168
169fs_setup:
170  - label: ephemeral0
171    filesystem: 'ext3'
172    device: 'ephemeral0'
173    partition: 'auto'
174  - label: mylabl2
175    filesystem: 'ext4'
176    device: '/dev/xvda1'
177  - cmd: mkfs -t %(filesystem)s -L %(label)s %(device)s
178    label: mylabl3
179    filesystem: 'btrfs'
180    device: '/dev/xvdh'
181
182# The general format is:
183#   fs_setup:
184#     - label: <LABEL>
185#       filesystem: <FS_TYPE>
186#       device: <DEVICE>
187#       partition: <PART_VALUE>
188#       overwrite: <OVERWRITE>
189#       replace_fs: <FS_TYPE>
190#
191# Where:
192#   <LABEL>: The filesystem label to be used. If set to None, no label is
193#     used.
194#
195#   <FS_TYPE>: The filesystem type. It is assumed that the there
196#     will be a "mkfs.<FS_TYPE>" that behaves likes "mkfs". On a standard
197#     Ubuntu Cloud Image, this means that you have the option of ext{2,3,4},
198#     and vfat by default.
199#
200#   <DEVICE>: The device name. Special names of 'ephemeralX' or 'swap'
201#     are allowed and the actual device is acquired from the cloud datasource.
202#     When using 'ephemeralX' (i.e. ephemeral0), make sure to leave the
203#     label as 'ephemeralX' otherwise there may be issues with the mounting
204#     of the ephemeral storage layer.
205#
206#     If you define the device as 'ephemeralX.Y' then Y will be interpetted
207#     as a partition value. However, ephermalX.0 is the _same_ as ephemeralX.
208#
209#   <PART_VALUE>:
210#     Partition definitions are overwritten if you use the '<DEVICE>.Y' notation.
211#
212#     The valid options are:
213#     "auto|any": tell cloud-init not to care whether there is a partition
214#       or not. Auto will use the first partition that does not contain a
215#       filesystem already. In the absence of a partition table, it will
216#       put it directly on the disk.
217#
218#       "auto": If a filesystem that matches the specification in terms of
219#       label, filesystem and device, then cloud-init will skip the creation
220#       of the filesystem.
221#
222#       "any": If a filesystem that matches the filesystem type and device,
223#       then cloud-init will skip the creation of the filesystem.
224#
225#       Devices are selected based on first-detected, starting with partitions
226#       and then the raw disk. Consider the following:
227#           NAME     FSTYPE LABEL
228#           xvdb
229#           |-xvdb1  ext4
230#           |-xvdb2
231#           |-xvdb3  btrfs  test
232#           \-xvdb4  ext4   test
233#
234#         If you ask for 'auto', label of 'test, and filesystem of 'ext4'
235#         then cloud-init will select the 2nd partition, even though there
236#         is a partition match at the 4th partition.
237#
238#         If you ask for 'any' and a label of 'test', then cloud-init will
239#         select the 1st partition.
240#
241#         If you ask for 'auto' and don't define label, then cloud-init will
242#         select the 1st partition.
243#
244#         In general, if you have a specific partition configuration in mind,
245#         you should define either the device or the partition number. 'auto'
246#         and 'any' are specifically intended for formatting ephemeral storage
247#         or for simple schemes.
248#
249#       "none": Put the filesystem directly on the device.
250#
251#       <NUM>: where NUM is the actual partition number.
252#
253#   <OVERWRITE>: Defines whether or not to overwrite any existing
254#     filesystem.
255#
256#     "true": Indiscriminately destroy any pre-existing filesystem. Use at
257#         your own peril.
258#
259#     "false": If an existing filesystem exists, skip the creation.
260#
261#   <REPLACE_FS>: This is a special directive, used for Microsoft Azure that
262#     instructs cloud-init to replace a filesystem of <FS_TYPE>. NOTE:
263#     unless you define a label, this requires the use of the 'any' partition
264#     directive.
265#
266# Behavior Caveat: The default behavior is to _check_ if the filesystem exists.
267#   If a filesystem matches the specification, then the operation is a no-op.

101#
102# Where:
103#   <DEVICE>: The name of the device. 'ephemeralX' and 'swap' are special
104#               values which are specific to the cloud. For these devices
105#               Cloud-init will look up what the real devices is and then
106#               use it.
107#
108#               For other devices, the kernel device name is used. At this
109#               time only simply kernel devices are supported, meaning
110#               that device mapper and other targets may not work.
111#
112#               Note: At this time, there is no handling or setup of
113#               device mapper targets.
114#
115#   table_type=<TYPE>: Currently the following are supported:
116#                   'mbr': default and setups a MS-DOS partition table
117#                   'gpt': setups a GPT partition table
118#
119#               Note: At this time only 'mbr' and 'gpt' partition tables
120#                   are allowed. It is anticipated in the future that
121#                   we'll also have "RAID" to create a mdadm RAID.
122#
123#   layout={...}: The device layout. This is a list of values, with the
124#               percentage of disk that partition will take.
125#               Valid options are:
126#                   [<SIZE>, [<SIZE>, <PART_TYPE]]
127#
128#               Where <SIZE> is the _percentage_ of the disk to use, while
129#               <PART_TYPE> is the numerical value of the partition type.
130#
131#               The following setups two partitions, with the first
132#               partition having a swap label, taking 1/3 of the disk space
133#               and the remainder being used as the second partition.
134#                 /dev/xvdh':
135#                   table_type: 'mbr'
136#                   layout:
137#                     - [33,82]
138#                     - 66
139#                   overwrite: True
140#
141#               When layout is "true" it means single partition the entire
142#               device.
143#
144#               When layout is "false" it means don't partition or ignore
145#               existing partitioning.
146#
147#               If layout is set to "true" and overwrite is set to "false",
148#               it will skip partitioning the device without a failure.
149#
150#   overwrite=<BOOL>: This describes whether to ride with safetys on and
151#               everything holstered.
152#
153#               'false' is the default, which means that:
154#                   1. The device will be checked for a partition table
155#                   2. The device will be checked for a filesystem
156#                   3. If either a partition of filesystem is found, then
157#                       the operation will be _skipped_.
158#
159#               'true' is cowboy mode. There are no checks and things are
160#                   done blindly. USE with caution, you can do things you
161#                   really, really don't want to do.

164# fs_setup: Setup the filesystem
165# ------------------------------
166#
167# fs_setup describes the how the filesystems are supposed to look.
168
169fs_setup:
170  - label: ephemeral0
171    filesystem: 'ext3'
172    device: 'ephemeral0'
173    partition: 'auto'
174  - label: mylabl2
175    filesystem: 'ext4'
176    device: '/dev/xvda1'
177  - cmd: mkfs -t %(filesystem)s -L %(label)s %(device)s
178    label: mylabl3
179    filesystem: 'btrfs'
180    device: '/dev/xvdh'
181
182# The general format is:
183#   fs_setup:
184#     - label: <LABEL>
185#       filesystem: <FS_TYPE>
186#       device: <DEVICE>
187#       partition: <PART_VALUE>
188#       overwrite: <OVERWRITE>
189#       replace_fs: <FS_TYPE>
190#
191# Where:
192#   <LABEL>: The filesystem label to be used. If set to None, no label is
193#     used.
194#
195#   <FS_TYPE>: The filesystem type. It is assumed that the there
196#     will be a "mkfs.<FS_TYPE>" that behaves likes "mkfs". On a standard
197#     Ubuntu Cloud Image, this means that you have the option of ext{2,3,4},
198#     and vfat by default.
199#
200#   <DEVICE>: The device name. Special names of 'ephemeralX' or 'swap'
201#     are allowed and the actual device is acquired from the cloud datasource.
202#     When using 'ephemeralX' (i.e. ephemeral0), make sure to leave the
203#     label as 'ephemeralX' otherwise there may be issues with the mounting
204#     of the ephemeral storage layer.
205#
206#     If you define the device as 'ephemeralX.Y' then Y will be interpetted
207#     as a partition value. However, ephermalX.0 is the _same_ as ephemeralX.
208#
209#   <PART_VALUE>:
210#     Partition definitions are overwritten if you use the '<DEVICE>.Y' notation.
211#
212#     The valid options are:
213#     "auto|any": tell cloud-init not to care whether there is a partition
214#       or not. Auto will use the first partition that does not contain a
215#       filesystem already. In the absence of a partition table, it will
216#       put it directly on the disk.
217#
218#       "auto": If a filesystem that matches the specification in terms of
219#       label, filesystem and device, then cloud-init will skip the creation
220#       of the filesystem.
221#
222#       "any": If a filesystem that matches the filesystem type and device,
223#       then cloud-init will skip the creation of the filesystem.
224#
225#       Devices are selected based on first-detected, starting with partitions
226#       and then the raw disk. Consider the following:
227#           NAME     FSTYPE LABEL
228#           xvdb
229#           |-xvdb1  ext4
230#           |-xvdb2
231#           |-xvdb3  btrfs  test
232#           \-xvdb4  ext4   test
233#
234#         If you ask for 'auto', label of 'test, and filesystem of 'ext4'
235#         then cloud-init will select the 2nd partition, even though there
236#         is a partition match at the 4th partition.
237#
238#         If you ask for 'any' and a label of 'test', then cloud-init will
239#         select the 1st partition.
240#
241#         If you ask for 'auto' and don't define label, then cloud-init will
242#         select the 1st partition.
243#
244#         In general, if you have a specific partition configuration in mind,
245#         you should define either the device or the partition number. 'auto'
246#         and 'any' are specifically intended for formatting ephemeral storage
247#         or for simple schemes.
248#
249#       "none": Put the filesystem directly on the device.
250#
251#       <NUM>: where NUM is the actual partition number.
252#
253#   <OVERWRITE>: Defines whether or not to overwrite any existing
254#     filesystem.
255#
256#     "true": Indiscriminately destroy any pre-existing filesystem. Use at
257#         your own peril.
258#
259#     "false": If an existing filesystem exists, skip the creation.
260#
261#   <REPLACE_FS>: This is a special directive, used for Microsoft Azure that
262#     instructs cloud-init to replace a filesystem of <FS_TYPE>. NOTE:
263#     unless you define a label, this requires the use of the 'any' partition
264#     directive.
265#
266# Behavior Caveat: The default behavior is to _check_ if the filesystem exists.
267#   If a filesystem matches the specification, then the operation is a no-op.
