git – Deploy software (or files) from git checkouts

Synopsis

  • Manage git checkouts of repositories to deploy files or software.

Requirements

The below requirements are needed on the host that executes this module.

  • git>=1.7.1 (the command line tool)

Parameters

Parameter Choices/Defaults Comments

accept_hostkey

boolean

added in 1.5

  • no

  • yes

if yes, ensure that "-o StrictHostKeyChecking=no" is present as an ssh option.

archive

-

added in 2.4

Specify archive file path with extension. If specified, creates an archive file of the specified format containing the tree structure for the source tree. Allowed archive formats ["zip", "tar.gz", "tar", "tgz"]

This will clone and perform git archive from local directory as not all git servers support git archive.

bare

boolean

added in 1.4

  • no

  • yes

if yes, repository will be created as a bare repo, otherwise it will be a standard repo with a workspace.

clone

boolean

added in 1.9

  • no
  • yes

If no, do not clone the repository if it does not exist locally

depth

-

Create a shallow clone with a history truncated to the specified number or revisions. The minimum possible value is 1, otherwise ignored. Needs git>=1.9.1 to work correctly.

dest

- / required

The path of where the repository should be checked out. This parameter is required, unless clone is set to no.

executable

-

added in 1.4

Path to git executable to use. If not supplied, the normal mechanism for resolving binary paths will be used.

force

boolean

  • no

  • yes

If yes, any modified files in the working repository will be discarded. Prior to 0.7, this was always 'yes' and could not be disabled. Prior to 1.9, the default was `yes`

key_file

-

added in 1.5

Specify an optional private key file path, on the target host, to use for the checkout.

recursive

boolean

added in 1.6

  • no
  • yes

if no, repository will be cloned without the --recursive option, skipping sub-modules.

reference

-

added in 1.4

Reference repository (see "git clone --reference ...")

refspec

-

added in 1.9

Add an additional refspec to be fetched. If version is set to a SHA-1 not reachable from any branch or tag, this option may be necessary to specify the ref containing the SHA-1. Uses the same syntax as the 'git fetch' command. An example value could be "refs/meta/config".

remote

-

Default:

"origin"

Name of the remote.

repo

- / required

git, SSH, or HTTP(S) protocol address of the git repository.


aliases: name

separate_git_dir

-

added in 2.7

The path to place the cloned repository. If specified, Git repository can be separated from working tree.

ssh_opts

-

added in 1.5

Creates a wrapper script and exports the path as GIT_SSH which git then automatically uses to override ssh arguments. An example value could be "-o StrictHostKeyChecking=no"

track_submodules

boolean

added in 1.8

  • no

  • yes

if yes, submodules will track the latest commit on their master branch (or other branch specified in .gitmodules). If no, submodules will be kept at the revision specified by the main project. This is equivalent to specifying the --remote flag to git submodule update.

umask

-

added in 2.2

The umask to set before doing any checkouts, or any other repository maintenance.

update

boolean

  • no
  • yes

If no, do not retrieve new revisions from the origin repository

Operations like archive will work on the existing (old) repository and might not respond to changes to the options version or remote.

verify_commit

boolean

added in 2.0

  • no

  • yes

if yes, when cloning or checking out a version verify the signature of a GPG signed commit. This requires git version>=2.1.0 to be installed. The commit MUST be signed and the public key MUST be present in the GPG keyring.

version

-

Default:

"HEAD"

What version of the repository to check out. This can be the literal string HEAD, a branch name, a tag name. It can also be a SHA-1 hash, in which case refspec needs to be specified if the given revision is not already available.



Notes

Note

  • If the task seems to be hanging, first verify remote host is in known_hosts. SSH will prompt user to authorize the first contact with a remote host. To avoid this prompt, one solution is to use the option accept_hostkey. Another solution is to add the remote host public key in /etc/ssh/ssh_known_hosts before calling the git module, with the following command: ssh-keyscan -H remote_host.com >> /etc/ssh/ssh_known_hosts.


Examples

# Example git checkout from Ansible Playbooks
- git:
    repo: 'https://foosball.example.org/path/to/repo.git'
    dest: /srv/checkout
    version: release-0.22

# Example read-write git checkout from github
- git:
    repo: ssh://[email protected]/mylogin/hello.git
    dest: /home/mylogin/hello

# Example just ensuring the repo checkout exists
- git:
    repo: 'https://foosball.example.org/path/to/repo.git'
    dest: /srv/checkout
    update: no

# Example just get information about the repository whether or not it has
# already been cloned locally.
- git:
    repo: 'https://foosball.example.org/path/to/repo.git'
    dest: /srv/checkout
    clone: no
    update: no

# Example checkout a github repo and use refspec to fetch all pull requests
- git:
    repo: https://github.com/ansible/ansible-examples.git
    dest: /src/ansible-examples
    refspec: '+refs/pull/*:refs/heads/*'

# Example Create git archive from repo
- git:
    repo: https://github.com/ansible/ansible-examples.git
    dest: /src/ansible-examples
    archive: /tmp/ansible-examples.zip

# Example clone a repo with separate git directory
- git:
    repo: https://github.com/ansible/ansible-examples.git
    dest: /src/ansible-examples
    separate_git_dir: /src/ansible-examples.git

Return Values

Common return values are documented here, the following are the fields unique to this module:
