Introducing GitHub Actions to your enterprise

You can plan how to roll out GitHub Actions in your enterprise.

About GitHub Actions for enterprises

GitHub Actions helps you automate tasks within your software development life cycle. With GitHub Actions, your enterprise can automate, customize, and execute your software development workflows like testing and deployments. For more information about the basics of GitHub Actions, see "Understanding GitHub Actions."

Before you introduce GitHub Actions to a large enterprise, you first need to plan your adoption and make decisions about how your enterprise will use GitHub Actions to best support your unique needs.

Governance and compliance

Your should create a plan to govern your enterprise's use of GitHub Actions and meet your compliance obligations.

Determine which actions your developers will be allowed to use. First, decide whether you'll allow third-party actions that were not created by GitHub. You can configure the actions that are allowed to run at the repository, organization, and enterprise levels and can choose to only allow actions that are created by GitHub. If you do allow third-party actions, you can limit allowed actions to those created by verified creators or a list of specific actions. For more information, see "Managing GitHub Actions settings for a repository", "Disabling or limiting GitHub Actions for your organization", and "Enforcing policies for GitHub Actions in your enterprise."

Consider combining OpenID Connect (OIDC) with reusable workflows to enforce consistent deployments across your repository, organization, or enterprise. You can do this by defining trust conditions on cloud roles based on reusable workflows. For more information, see "Using OpenID Connect with reusable workflows."

You can access information about activity related to GitHub Actions in the audit logs for your enterprise. If your business needs require retaining audit logs for longer than six months, plan how you'll export and store this data outside of GitHub. For more information, see "Streaming the audit logs for organizations in your enterprise."

You should plan your approach to security hardening for GitHub Actions.

Security hardening individual workflows and repositories

Make a plan to enforce good security practices for people using GitHub Actions features within your enterprise. For more information about these practices, see "Security hardening for GitHub Actions."

You can also encourage reuse of workflows that have already been evaluated for security. For more information, see "Innersourcing."

Securing access to secrets and deployment resources

You should plan where you'll store your secrets. We recommend storing secrets in GitHub, but you might choose to store secrets in a cloud provider.

In GitHub, you can store secrets at the repository or organization level. Secrets at the repository level can be limited to workflows in certain environments, such as production or testing. For more information, see "Encrypted secrets."

You should consider adding manual approval protection for sensitive environments, so that workflows must be approved before getting access to the environments' secrets. For more information, see "Using environments for deployments."

Security considerations for third-party actions

There is significant risk in sourcing actions from third-party repositories on GitHub. If you do allow any third-party actions, you should create internal guidelines that enourage your team to follow best practices, such as pinning actions to the full commit SHA. For more information, see "Using third-party actions."


Think about how your enterprise can use features of GitHub Actions to innersource workflows. Innersourcing is a way to incorporate the benefits of open source methodologies into your internal software development cycle. For more information, see An introduction to innersource in GitHub Resources.

With reusable workflows, your team can call one workflow from another workflow, avoiding exact duplication. Reusable workflows promote best practice by helping your team use workflows that are well designed and have already been tested. For more information, see "Reusing workflows."

To provide a starting place for developers building new workflows, you can use workflow templates. This not only saves time for your developers, but promotes consistency and best practice across your enterprise. For more information, see "Creating workflow templates."

Whenever your workflow developers want to use an action that's stored in a private repository, they must configure the workflow to clone the repository first. To reduce the number of repositories that must be cloned, consider grouping commonly used actions in a single repository. For more information, see "About custom actions."

Managing resources

You should plan for how you'll manage the resources required to use GitHub Actions.


GitHub Actions workflows require runners. You can choose to use GitHub-hosted runners or self-hosted runners. GitHub-hosted runners are convenient because they are managed by GitHub, who handles maintenance and upgrades for you. However, you may want to consider self-hosted runners if you need to run a workflow that will access resources behind your firewall or you want more control over the resources, configuration, or geographic location of your runner machines. For more information, see "About GitHub-hosted runners" and "About self-hosted runners."

If you are using self-hosted runners, you have to decide whether you want to use physical machines, virtual machines, or containers. Physical machines will retain remnants of previous jobs, and so will virtual machines unless you use a fresh image for each job or clean up the machines after each job run. If you choose containers, you should be aware that the runner auto-updating will shut down the container, which can cause workflows to fail. You should come up with a solution for this by preventing auto-updates or skipping the command to kill the container.

You also have to decide where to add each runner. You can add a self-hosted runner to an individual repository, or you can make the runner available to an entire organization or your entire enterprise. Adding runners at the organization or enterprise levels allows sharing of runners, which might reduce the size of your runner infrastructure. You can use policies to limit access to self-hosted runners at the organization and enterprise levels by assigning groups of runners to specific repositories or organizations. For more information, see "Adding self-hosted runners" and "Managing access to self-hosted runners using groups."

You should consider using autoscaling to automatically increase or decrease the number of available self-hosted runners. For more information, see "Autoscaling with self-hosted runners."

Finally, you should consider security hardening for self-hosted runners. For more information, see "Security hardening for GitHub Actions."


Artifacts enable you to share data between jobs in a workflow and store data once that workflow has completed. For more information, see "Storing workflow data as artifacts."

By default, GitHub Enterprise Cloud stores build logs and artifacts for 90 days, and this retention period can be customized. For more information, see "Usage limits, billing, and administration".

If you want to retain logs and artifacts longer than the upper limit you can configure in GitHub Enterprise Cloud, you'll have to plan how to export and store the data.

Some storage is included in your subscription, but additional storage will affect your bill. You should plan for this cost. For more information, see "About billing for GitHub Actions."

Tracking usage

You should consider making a plan to track your enterprise's usage of GitHub Actions, such as how often workflows are running, how many of those runs are passing and failing, and which repositories are using which workflows.

You can see basic details of storage and data transfer usage of GitHub Actions for each organization in your enterprise via your billing settings. For more information, see "Viewing your GitHub Actions usage."

For more detailed usage data, you can use webhooks to subscribe to information about workflow jobs and workflow runs. For more information, see "About webhooks."

Make a plan for how your enterprise can pass the information from these webhooks into a data archiving system. You can consider using "CEDAR.GitHub.Collector", an open source tool that collects and processes webhook data from GitHub. For more information, see the Microsoft/CEDAR.GitHub.Collector repository.

You should also plan how you'll enable your teams to get the data they need from your archiving system.
