Git Resource

Tracks the commits in a git repository.

Source Configuration

  • uri: Required. The location of the repository.

  • branch: Required. The branch to track.

  • private_key: Optional. Private key to use when pulling/pushing. Example:

    private_key: |
      -----BEGIN RSA PRIVATE KEY-----
      MIIEowIBAAKCAQEAtCS10/f7W7lkQaSgD/mVeaSOvSF9ql4hf/zfMwfVGgHWjj+W
      <Lots more text>
      DWiJL+OFeg9kawcUL6hQ8JeXPhlImG6RTUffma9+iGQyyBMCGd1l
      -----END RSA PRIVATE KEY-----
    

    Note: You can also use pipeline templating to hide this private key in source control. (For more information: https://concourse.ci/fly-set-pipeline.html)

  • username: Optional. Username for HTTP(S) auth when pulling/pushing. This is needed when only HTTP/HTTPS protocol for git is available (which does not support private key auth) and auth is required.

  • password: Optional. Password for HTTP(S) auth when pulling/pushing.

    Note: You can also use pipeline templating to hide this password in source control. (For more information: https://concourse.ci/fly-set-pipeline.html)

  • paths: Optional. If specified (as a list of glob patterns), only changes to the specified files will yield new versions from check.

  • ignore_paths: Optional. The inverse of paths; changes to the specified files are ignored.

    Note that if you want to push commits that change these files via a put, the commit will still be "detected", as check and put both introduce versions. To avoid this you should define a second resource that you use for commits that change files that you don't want to feed back into your pipeline - think of one as read-only (with ignore_paths) and one as write-only (which shouldn't need it).

  • skip_ssl_verification: Optional. Skips git ssl verification by exporting GIT_SSL_NO_VERIFY=true.

  • tag_filter: Optional. If specified, the resource will only detect commits that have a tag matching the specified expression. Patterns are glob(7) compatible (as in, bash compatible).

  • git_config: Optional. If specified as (list of pairs name and value) it will configure git global options, setting each name with each value.

    This can be useful to set options like credential.helper or similar.

    See the git-config(1) manual page for more information and documentation of existing git options.

  • disable_ci_skip: Optional. Allows for commits that have been labeled with [ci skip] or [skip ci] previously to be discovered by the resource.

  • commit_verification_keys: Optional. Array of GPG public keys that the resource will check against to verify the commit (details below).

  • commit_verification_key_ids: Optional. Array of GPG public key ids that the resource will check against to verify the commit (details below). The corresponding keys will be fetched from the key server specified in gpg_keyserver. The ids can be short id, long id or fingerprint.

  • gpg_keyserver: Optional. GPG keyserver to download the public keys from. Defaults to hkp:///keys.gnupg.net/.

Example

Resource configuration for a private repo:

resources:
- name: source-code
  type: git
  source:
    uri: git@github.com:concourse/git-resource.git
    branch: master
    private_key: |
      -----BEGIN RSA PRIVATE KEY-----
      MIIEowIBAAKCAQEAtCS10/f7W7lkQaSgD/mVeaSOvSF9ql4hf/zfMwfVGgHWjj+W
      <Lots more text>
      DWiJL+OFeg9kawcUL6hQ8JeXPhlImG6RTUffma9+iGQyyBMCGd1l
      -----END RSA PRIVATE KEY-----
    git_config:
    - name: core.bigFileThreshold
      value: 10m
    disable_ci_skip: true

Fetching a repo with only 100 commits of history:

- get: source-code
  params: {depth: 100}

Pushing local commits to the repo:

- get: some-other-repo
- put: source-code
  params: {repository: some-other-repo}

Behavior

check: Check for new commits.

The repository is cloned (or pulled if already present), and any commits from the given version on are returned. If no version is given, the ref for HEAD is returned.

Any commits that contain the string [ci skip] will be ignored. This allows you to commit to your repository without triggering a new version.

in: Clone the repository, at the given ref.

Clones the repository to the destination, and locks it down to a given ref. It will return the same given ref as version.

Submodules are initialized and updated recursively.

Parameters

  • depth: Optional. If a positive integer is given, shallow clone the repository using the --depth option. Using this flag voids your warranty. Some things will stop working unless we have the entire history.

  • submodules: Optional. If none, submodules will not be fetched. If specified as a list of paths, only the given paths will be fetched. If not specified, or if all is explicitly specified, all submodules are fetched.

  • disable_git_lfs: Optional. If true, will not fetch Git LFS files.

GPG signature verification

If commit_verification_keys or commit_verification_key_ids is specified in the source configuration, it will additionally verify that the resulting commit has been GPG signed by one of the specified keys. It will error if this is not the case.

out: Push to a repository.

Push the checked-out reference to the source's URI and branch. All tags are also pushed to the source. If a fast-forward for the branch is not possible and the rebase parameter is not provided, the push will fail.

Parameters

  • repository: Required. The path of the repository to push to the source.

  • rebase: Optional. If pushing fails with non-fast-forward, continuously attempt rebasing and pushing.

  • tag: Optional. If this is set then HEAD will be tagged. The value should be a path to a file containing the name of the tag.

  • only_tag: Optional. When set to 'true' push only the tags of a repo.

  • tag_prefix: Optional. If specified, the tag read from the file will be prepended with this string. This is useful for adding v in front of version numbers.

  • force: Optional. When set to 'true' this will force the branch to be pushed regardless of the upstream state.

  • annotate: Optional. If specified the tag will be an annotated tag rather than a lightweight tag. The value should be a path to a file containing the annotation message.
