Adding a git repository

In the piped configuration file, we specify the list of Git repositories should be handled by the piped. A Git repository contains one or more deployable applications where each application is put inside a directory called as application directory. That directory contains an application configuration file as well as application manifests. The piped periodically checks the new commits and fetches the needed manifests from those repositories for executing the deployment.

A single piped can be configured to handle one or more Git repositories. In order to enable a new Git repository, let’s add a new GitRepository block to the repositories field in the piped configuration file.

For example, with the following snippet, piped will take the master branch of pipe-cd/examples repository as a target Git repository for doing deployments.

apiVersion: pipecd.dev/v1beta1
kind: Piped
spec:
  ...
  repositories:
    - repoId: examples
      remote: git@github.com:pipe-cd/examples.git
      branch: master

In most of the cases, we want to deal with private Git repositories. For accessing those private repositories, piped needs a private SSH key, which can be configured while installing with secret.sshKey in the Helm chart.

helm install dev-piped pipecd/piped --version={VERSION} \
  --set-file config.data={PATH_TO_PIPED_CONFIG_FILE} \
  --set-file secret.data.piped-key={PATH_TO_PIPED_KEY_FILE} \
  --set-file secret.data.ssh-key={PATH_TO_PRIVATE_SSH_KEY_FILE}

You can see this configuration reference for more configurable fields about Git commands.

Currently, piped allows configuring only one private SSH key for all specified Git repositories. So you can configure the same SSH key for all of those private repositories, or break them into separate pipeds. In the near future, we also want to update piped to support loading multiple SSH keys.
