| `git` Tekton Task | ||
| ----------------- | ||
|
|
||
| The `git` Task will clone and prepare a Git repository on the `output` Workspace. By default the Git repository (`URL`) will be cloned on the root of the Workspace, but you can alter the clone location using the `SUBDIRECTORY` parameter, and [other settings](#parameters). | ||
|
|
||
| A quick usage example is: | ||
|
|
||
| ```yaml | ||
| --- | ||
| apiVersion: tekton.dev/v1beta1 | ||
| kind: TaskRun | ||
| metadata: {} | ||
| spec: | ||
| taskRef: | ||
| name: git | ||
| params: | ||
| - name: URL | ||
| value: https://github.com/openshift-pipelines/task-git.git | ||
| workspaces: | ||
| - name: output | ||
| emptyDir: {} | ||
| ``` | ||
| Please consider the [Workspaces](#workspaces), [Parameters](#parameters) and [Results](#results) described below. | ||
| # Workspaces | ||
| A single Workspace is required for this Task, while the optional Workspaces will allow advanced Git configuration and authentication. | ||
| ## `output` | ||
|
|
||
| The `output` is a required Workspace, represents the primary location where the Git repository data will be stored, and later on, this Workspace will be monted in subsequent Pipeline's Task. | ||
|
|
||
| Knowing the Workspace data will be employed on other Tasks, the recommended approach is using a [persistent volume][tektonPVC], for instance a [`PersistentVolumeClaim` (PVC)][k8sPVC]. | ||
|
|
||
| ## Authentication Workspaces | ||
|
|
||
| The recommended approach to authentication is using the [default mechanisms supported by Tekton Pipeline][tektonAuthentication], please consider it as your first option. | ||
|
|
||
| More advanced use-cases may require different methods of interacting with private repositories, the following Workspaces are meant to support advanced Git configuration and authentication. | ||
|
|
||
| ### `basic-auth` (HTTP/SSH) | ||
|
|
||
| The `basic-auth` is a optional Workspace to provide Git credentials and configuration. | ||
|
|
||
| The following Workspace files (items) are shared with Git before cloning the repository, the Task copies the files to the Git user home directory, configured by the parameter `USER_HOME`. | ||
|
|
||
| | Workspace File | Required | Description | | ||
| | :----------------- | :------: | :------------------------------------- | | ||
| | `.git-credentials` | `true` | [Git credentials file][gitCredentials] | | ||
| | `.gitconfig` | `true` | [Git configuration file][gitConfig] | | ||
|
|
||
| Typically, this type of data is stored as a Kubernetes Secret. For example: | ||
|
|
||
| ```bash | ||
| kubectl create secret generic basic-auth-ex \ | ||
| --from-file=".git-credentials=${HOME}/.git-credentials" \ | ||
| --from-file=".gitconfig=${HOME}/.gitconfig" | ||
| ``` | ||
|
|
||
| Then, you can [reference the Secret][tektonWorkspaceSecret] as the `basic-auth` Workspace. | ||
|
|
||
| ### `ssh-directory` (SSH) | ||
|
|
||
| The `ssh-directory` is a optional Workspace, meant to store the files commonly found on a [`~/.ssh` directory][dotSSHDirectory], when informed, the whole directory will be copied into the Git's home (configured by the parameter `USER_HOME`). | ||
|
|
||
| During the `prepare` step you can see the details about what's being copied, please consider the output log snippet below. For more verbose logging set the peramater `VERBOSE` to `true`. | ||
|
|
||
| ``` | ||
| ---> Phase: Copying '.ssh' from ssh-directory workspace ('/workspaces/ssh-directory')... | ||
| '/workspaces/ssh-directory' -> '/home/git/.ssh' | ||
| '/workspaces/ssh-directory/config' -> '/home/git/.ssh/config' | ||
| mode of '/home/git/.ssh' changed from 0755 (rwxr-xr-x) to 0700 (rwx------) | ||
| mode of '/home/git/.ssh/config' changed from 0644 (rw-r--r--) to 0400 (r--------) | ||
|
|
||
| ``` | ||
| It's recommended storing this type of data as a Kubernetes Secret, like the following example: | ||
| ```bash | ||
| kubectl create secret generic ssh-directory-ex \ | ||
| --from-file="config=${HOME}/.ssh/config" \ | ||
| --from-file="authorized_keys=${HOME}/.ssh/authorized_keys" | ||
| ``` | ||
|
|
||
| Then, you can [reference the Secret][tektonWorkspaceSecret] as the `ssh-directory` Workspace. | ||
|
|
||
| ### `ssl-ca-directory` (mTLS) | ||
|
|
||
| The `ssl-ca-directory` is a optional Workspace to store a additional [Certificate Authority (CA)][tlsCA] bundles, commonly `.pem` or `.crt` files. The exact bundle file name is defined by the parameter `CRT_FILENAME`. | ||
|
|
||
| Before running the Git clone command, the [`GIT_SSL_CAINFO` environment variable][gitSSLCAInfo] is exported with the full path to the `CRT_FILENAME` in the `ssl-ca-directory` Workspace. | ||
|
|
||
| You can observe the setting taking place on the beggining of the `git-clone` step: | ||
|
|
||
| ``` | ||
| phase 'Exporting custom CA certificate "GIT_SSL_CAINFO=/workspaces/ssl-ca-directory/ca-bundle.crt"' | ||
| ``` | ||
|
|
||
| This is a sensitive information and therefore it's recommended to store as a Kubernetes Secret, please consider the previous examples to create Secrets with the `--from-file` option. | ||
|
|
||
| Finally, you can [reference the Secret][tektonWorkspaceSecret] as the `ssl-ca-directory` Workspace. | ||
|
|
||
