Options

Options can be passed using the inputs of this action or the corresponding environment variables. When both are passed, the input takes precedence over the environment variable. For the available environment variables, see the Renovate Self-Hosted Configuration docs.

configurationFile

Configuration file to configure Renovate ("global" config) in JavaScript or JSON format. It is recommended to not name it one of the repository configuration filenames listed in the Renovate Docs for Configuration Options.

Config examples can be found in the example directory.

The configurations that can be done in this file consists of two parts, as listed below. Refer to the links to the Renovate Docs for all options.

1. Self-Hosted Configuration Options
2. Configuration Options

The branchPrefix option is important to configure and should be configured to a value other than the default to prevent interference with e.g. the Renovate GitHub App.

If you want to use this with just the single configuration file, make sure to include the following two configuration lines. This disables the requirement of a configuration file for the repository and disables onboarding.

  onboarding: false,
  requireConfig: false,

docker-cmd-file

Specify a command to run when the image start. By default the image run renovate. This option is useful to customize the image before running renovate. It must be an existing executable file on the local system. It will be mounted to the docker container.

For example you can create a simple script like this one (let's call it renovate-entrypoint.sh).

#!/bin/bash

apt update

apt install -y build-essential libpq-dev

runuser -u ubuntu renovate

Now use this action

....
jobs:
  renovate:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4.2.2
      - name: Self-hosted Renovate
        uses: renovatebot/github-action@v41.0.3
        with:
          docker-cmd-file: .github/renovate-entrypoint.sh
          docker-user: root
          token: ${{ secrets.RENOVATE_TOKEN }}

docker-network

Specify a network to run container in.

You can use ${{ job.container.network }} to run renovate container in the same network as other containers for this job, or set it to host to run in the same network as github runner, or specify any custom network.

docker-socket-host-path

Allows the overriding of the host path for the Docker socket that is mounted into the container. Useful on systems where the host Docker socket is located somewhere other than /var/run/docker.sock (the default). Only applicable when mount-docker-socket is true.

docker-user

Specify a user (or user-id) to run docker command.

You can use it with docker-cmd-file in order to start the image as root, do some customization and switch back to a unprivileged user.

docker-volumes

Specify volume mounts. Defaults to /tmp:/tmp. The volume mounts are separated through ;.

This sample will mount /tmp:/tmp and /foo:/bar.

....
jobs:
  renovate:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4.2.2
      - name: Self-hosted Renovate
        uses: renovatebot/github-action@v41.0.3
        with:
          token: ${{ secrets.RENOVATE_TOKEN }}
          docker-volumes: |
            /tmp:/tmp ;
            /foo:/bar

env-regex

Allows to configure the regex to define which environment variables are passed to the renovate container. See Passing other environment variables section for more details.

mount-docker-socket

Default to false. If set to true the action will mount the Docker socket inside the renovate container so that the commands can use Docker. Can be useful for postUpgradeTasks's commands. Also add the user inside the renovate container to the docker group for socket permissions.

token

Generate a Personal Access Token (classic), with the repo:public_repo scope for only public repositories or the repo scope for public and private repositories, and add it to Secrets (repository settings) as RENOVATE_TOKEN. You can also create a token without a specific scope, which gives read-only access to public repositories, for testing. This token is only used by Renovate, see the token configuration, and gives it access to the repositories. The name of the secret can be anything as long as it matches the argument given to the token option.

Note that Renovate cannot currently use Fine-grained Personal Access Tokens since they do not support the GitHub GraphQL API, yet.

Note that the GITHUB_TOKEN secret can't be used for authenticating Renovate because it has too restrictive permissions. In particular, using the GITHUB_TOKEN to create a new Pull Request from more types of Github Workflows results in Pull Requests that do not trigger your Pull Request and Push CI events.

If you want to use the github-actions manager, you must setup a special token with some requirements.

renovate-image

The Renovate Docker image name to use. If omitted the action will use the ghcr.io/renovatebot/renovate:<renovate-version> Docker image name otherwise. If a Docker image name is defined, the action will use that name to pull the image.

This sample will use myproxyhub.domain.com/renovate/renovate:<renovate-version> image.

....
jobs:
  renovate:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4.2.2
      - name: Self-hosted Renovate
        uses: renovatebot/github-action@v41.0.3
        with:
          renovate-image: myproxyhub.domain.com/renovate/renovate
          token: ${{ secrets.RENOVATE_TOKEN }}

This sample will use ghcr.io/renovatebot/renovate:<renovate-version> image.

....
jobs:
  renovate:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4.2.2
      - name: Self-hosted Renovate
        uses: renovatebot/github-action@v41.0.3
        with:
          token: ${{ secrets.RENOVATE_TOKEN }}

renovate-version

The Renovate version to use. If omitted the action will use the default version Docker tag. Check the available tags on Docker Hub.

This sample will use ghcr.io/renovatebot/renovate:39.19.1 image.

....
jobs:
  renovate:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4.2.2
      - name: Self-hosted Renovate
        uses: renovatebot/github-action@v41.0.3
        with:
          renovate-version: 39.19.1
          token: ${{ secrets.RENOVATE_TOKEN }}

This sample will use ghcr.io/renovatebot/renovate:full image.

....
jobs:
  renovate:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4.2.2
      - name: Self-hosted Renovate
        uses: renovatebot/github-action@v41.0.3
        with:
          renovate-version: full
          token: ${{ secrets.RENOVATE_TOKEN }}

We recommend you pin the version of Renovate to a full version or a full checksum, and use Renovate's regex manager to create PRs to update the pinned version. See .github/workflows/build.yml for an example of how to do this.

Example

This example uses a Personal Access Token and will run every 15 minutes. The Personal Access token is configured as a GitHub secret named RENOVATE_TOKEN. This example uses the example/renovate-config.js file as configuration. Live examples with more advanced configurations of this action can be found in the following repositories:

• vidavidorra/renovate
• jenkinsci/helm-charts

Remark Update the action version to the most current, see here for latest release.

name: Renovate
on:
  schedule:
    # The "*" (#42, asterisk) character has special semantics in YAML, so this
    # string has to be quoted.
    - cron: '0/15 * * * *'
jobs:
  renovate:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4.2.2
      - name: Self-hosted Renovate
        uses: renovatebot/github-action@v41.0.3
        with:
          configurationFile: example/renovate-config.js
          token: ${{ secrets.RENOVATE_TOKEN }}

Example for GitHub Enterprise

If you want to use the Renovate Action on a GitHub Enterprise instance you have to add the following environment variable:

....
      - name: Self-hosted Renovate
        uses: renovatebot/github-action@v41.0.3
        with:
          configurationFile: example/renovate-config.js
          token: ${{ secrets.RENOVATE_TOKEN }}
        env:
          RENOVATE_ENDPOINT: "https://git.your-company.com/api/v3"

Example with GitHub App

Instead of using a Personal Access Token (PAT) that is tied to a particular user you can use a GitHub App where permissions can be even better tuned. Create a new app and configure the app permissions and your config.js as described in the Renovate documentation.

Generate and download a new private key for the app, adding the contents of the downloaded .pem file to Secrets (repository settings) with the name private_key and app ID as a secret with name app_id.

Adjust your Renovate configuration file to specify the username of your bot.

Going forward we will be using the actions/create-github-app-token action in order to exchange the GitHub App certificate for an access token that Renovate can use.

The final workflow will look like this:

name: Renovate
on:
  schedule:
    # The "*" (#42, asterisk) character has special semantics in YAML, so this
    # string has to be quoted.
    - cron: '0/15 * * * *'
jobs:
  renovate:
    runs-on: ubuntu-latest
    steps:
      - name: Get token
        id: get_token
        uses: actions/create-github-app-token@v1
        with:
          private-key: ${{ secrets.private_key }}
          app-id: ${{ secrets.app_id }}
          owner: ${{ github.repository_owner }}
          repositories: 'repo1,repo2'

      - name: Checkout
        uses: actions/checkout@v4.2.2

      - name: Self-hosted Renovate
        uses: renovatebot/github-action@v41.0.3
        with:
          configurationFile: example/renovate-config.js
          token: '${{ steps.get_token.outputs.token }}'

Commit signing with GitHub App

Renovate can sign commits when deployed as a GitHub App by utilizing GitHub's API-based commits. To activate this, ensure that platformCommit is set to true in global config. If a configuration file is defined, include platformCommit: true to activate this feature. For example:

- name: Self-hosted Renovate
  uses: renovatebot/github-action@v41.0.3
  with:
    token: '${{ steps.get_token.outputs.token }}'
  env:
    RENOVATE_PLATFORM_COMMIT: 'true'

Environment Variables

If you wish to pass through environment variables through to the Docker container that powers this action you need to prefix the environment variable with RENOVATE_.

For example if you wish to pass through some credentials for a host rule to the config.js then you should do so like this.

1. In your workflow pass in the environment variable

   ....
   jobs:
     renovate:
       runs-on: ubuntu-latest
       steps:
         - name: Checkout
           uses: actions/checkout@v4.2.2
         - name: Self-hosted Renovate
           uses: renovatebot/github-action@v41.0.3
           with:
             configurationFile: example/renovate-config.js
             token: ${{ secrets.RENOVATE_TOKEN }}
           env:
             RENOVATE_TFE_TOKEN: ${{ secrets.MY_TFE_TOKEN }}
   

2. In example/renovate-config.js include the hostRules block

   module.exports = {
     hostRules: [
       {
         hostType: 'terraform-module',
         matchHost: 'app.terraform.io',
         token: process.env.RENOVATE_TFE_TOKEN,
       },
     ],
   };
   

Passing other environment variables

If you want to pass other variables to the Docker container use the env-regex input to override the regular expression that is used to allow environment variables.

In your workflow pass the environment variable and whitelist it by specifying the env-regex:

....
jobs:
  renovate:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4.2.2
      - name: Self-hosted Renovate
        uses: renovatebot/github-action@v41.0.3
        with:
          configurationFile: example/renovate-config.js
          token: ${{ secrets.RENOVATE_TOKEN }}
          env-regex: "^(?:RENOVATE_\\w+|LOG_LEVEL|GITHUB_COM_TOKEN|NODE_OPTIONS|AWS_TOKEN)$"
        env:
          AWS_TOKEN: ${{ secrets.AWS_TOKEN }}

Persisting the repository cache

In some cases, Renovate can update PRs more frequently than you expect. The repository cache can help with this issue. You need a few things to persist this cache in GitHub actions:

1. Enable the repositoryCache option via env vars or renovate.json.
2. Persist /tmp/renovate/cache/renovate/repository as an artifact.
3. Restore the artifact before renovate runs.

Below is a workflow example with caching.

Note that while archiving and compressing the cache is more performant, especially if you need to handle lots of files within the cache, it's not strictly necessary. You could simplify this workflow and only upload and download a single artifact file (or directory) with a direct path (e.g. /tmp/renovate/cache/renovate/repository/github/$org/$repo.json). However, you'll still need to set the correct permissions with chown as shown in the example.

name: Renovate
on:
  # This lets you dispatch a renovate job with different cache options if you want to reset or disable the cache manually.
  workflow_dispatch:
    inputs:
      repoCache:
        description: 'Reset or disable the cache?'
        type: choice
        default: enabled
        options:
          - enabled
          - disabled
          - reset
  schedule:
    # Run every 30 minutes:
    - cron: '0,30 * * * *'

# Adding these as env variables makes it easy to re-use them in different steps and in bash.
env:
  cache_archive: renovate_cache.tar.gz
  # This is the dir renovate provides -- if we set our own directory via cacheDir, we can run into permissions issues.
  # It is also possible to cache a higher level of the directory, but it has minimal benefit. While renovate execution
  # time gets faster, it also takes longer to upload the cache as it grows bigger.
  cache_dir: /tmp/renovate/cache/renovate/repository
  # This can be manually changed to bust the cache if neccessary.
  cache_key: renovate-cache

jobs:
  renovate:
    name: Renovate
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3

      # This third party action allows you to download the cache artifact from different workflow runs
      # Note that actions/cache doesn't work well because the cache key would need to be computed from
      # a file within the cache, meaning there would never be any data to restore. With other keys, the
      # cache wouldn't necessarily upload when it changes. actions/download-artifact also doesn't work
      # because it only handles artifacts uploaded in the same run, and we want to restore from the
      # previous successful run.
      - uses: dawidd6/action-download-artifact@v2
        if: github.event.inputs.repoCache != 'disabled'
        continue-on-error: true
        with:
          name: ${{ env.cache_key }}
          path: cache-download

      # Using tar to compress and extract the archive isn't strictly necessary, but it can improve
      # performance significantly when uploading artifacts with lots of files.
      - name: Extract renovate cache
        run: |
          set -x
          # Skip if no cache is set, such as the first time it runs.
          if [ ! -d cache-download ] ; then
            echo "No cache found."
            exit 0
          fi

          # Make sure the directory exists, and extract it there. Note that it's nested in the download directory.
          mkdir -p $cache_dir
          tar -xzf cache-download/$cache_archive -C $cache_dir

          # Unfortunately, the permissions expected within renovate's docker container
          # are different than the ones given after the cache is restored. We have to
          # change ownership to solve this. We also need to have correct permissions in
          # the entire /tmp/renovate tree, not just the section with the repo cache.
          sudo chown -R 12021:0 /tmp/renovate/
          ls -R $cache_dir

      - uses: renovatebot/github-action@v41.0.3
        with:
          configurationFile: renovate.json5
          token: ${{ secrets.RENOVATE_TOKEN }}

          RENOVATE_REPOSITORY_CACHE: ${{ github.event.inputs.repoCache || 'enabled' }}

      # Compression helps performance in the upload step!
      - name: Compress renovate cache
        run: |
          ls $cache_dir
          # The -C is important -- otherwise we end up extracting the files with

          # for long. Just make sure this value is large enough that multiple renovate
          # runs can happen before older cache archives are deleted.
          retention-days: 1

Troubleshooting

Debug logging

In case of issues, it's always a good idea to enable debug logging first. To enable debug logging, add the environment variable LOG_LEVEL: 'debug' to the action:

- name: Self-hosted Renovate
  uses: renovatebot/github-action@v41.0.3
  with:
    configurationFile: example/renovate-config.js
    token: ${{ secrets.RENOVATE_TOKEN }}
  env:
    LOG_LEVEL: 'debug'

Special token requirements when using the github-actions manager

If you want to use the github-actions manager in Renovate, ensure that the token you provide contains the workflow scope. Otherwise, GitHub does not allow Renovate to update workflow files and therefore it will be unable to create update PRs for affected packages (like actions/checkout or renovatebot/github-action itself).
