The semantic-release command must be executed only after all the tests in the CI build pass. If the build runs multiple jobs (for example to test on multiple Operating Systems or Node versions) the CI has to be configured to guarantee that the semantic-release command is executed only after all jobs are successful.
Here are a few examples of the CI services that can be used to achieve this:
- Travis Build Stages
- CircleCI Workflows
- GitHub Actions
- Codeship Deployment Pipelines
- GitLab Pipelines
- Codefresh Pipelines
- Wercker Workflows
- GoCD Pipelines.
See CI configuration recipes for more details.
semantic-release requires push access to the project Git repository in order to create Git tags. The Git authentication can be set with one of the following environment variables:
| Variable | Description |
|---|---|
GH_TOKEN or GITHUB_TOKEN |
A GitHub personal access token. |
GL_TOKEN or GITLAB_TOKEN |
A GitLab personal access token. |
BB_TOKEN or BITBUCKET_TOKEN |
A Bitbucket personal access token. |
BB_TOKEN_BASIC_AUTH or BITBUCKET_TOKEN_BASIC_AUTH |
A Bitbucket personal access token with basic auth support. For clarification user:token has to be the value of this env. |
GIT_CREDENTIALS |
URL encoded Git username and password in the format <username>:<password>. The username and password must each be individually URL encoded, not the : separating them. |
Alternatively the Git authentication can be set up via SSH keys.
Most semantic-release plugins require setting up authentication in order to publish to a package manager registry. The default @semantic-release/npm and @semantic-release/github plugins require the following environment variables:
| Variable | Description |
|---|---|
NPM_TOKEN |
npm token created via npm token create. Note: Only the auth-only level of npm two-factor authentication is supported. |
GH_TOKEN |
GitHub authentication token. Note: Only the personal token authentication is supported. |
See each plugin's documentation for the environment variables required.
The authentication token/credentials have to be made available in the CI service via environment variables.
See CI configuration recipes for more details on how to configure environment variables in your CI service.
Note: The environment variables GH_TOKEN, GITHUB_TOKEN, GL_TOKEN and GITLAB_TOKEN can be used for both the Git authentication and the API authentication required by @semantic-release/github and @semantic-release/gitlab.
