GitLab CI
Jobs authenticate with the project and ref they ran from.
Jobs authenticate with the project and ref they ran from.
What proves the identity
The token has to come from https://gitlab.com, and its sub claim has to match the workload you named. penv compares that claim byte for byte, with no wildcards.
Every token also has to name your workspace as its audience. Ask for this audience and no other. A token requested for two audiences fails every exchange.
What the console asks for
| Field | Example | Advanced | What it pins |
|---|---|---|---|
| Project path | acme/api | no | The group and project from your project's URL. |
| Branch | main | no | Only jobs on this branch authenticate. |
| GitLab host | https://gitlab.com | yes | Self-managed installs use their own URL, and must be reachable from the internet. |
| Ref type | branch | yes | One of Branch, Tag. |
A field marked advanced carries a default and stays behind the disclosure until you open it.
The console also asks which project and environment this identity reaches and which role it gets, with the credential lifetime behind Advanced.
What the trust holds
Built from the example answers above:
| What | Value |
|---|---|
| Issuer | https://gitlab.com |
| Claim compared | sub |
| Subject | project_path:acme/api:ref_type:branch:ref:main |
| Identity name | gitlab-acme-api-main |
penv names the identity for you, so the form never asks for one.
The snippet the console prints
pull-secrets:
id_tokens:
PENV_ID_TOKEN:
aud: YOUR_WORKSPACE_ID
script:
- |
T="$PENV_ID_TOKEN"
C=$(curl -sS "https://penv.cloud/api/v1/auth/oidc" \
-H 'content-type: application/json' \
-d "{\"token\":\"$T\"}" | jq -r .credential)
PENV_TOKEN="$C" penv pullThe snippet finishes with penv pull, which writes a file. penv run is the path the docs teach for a process, and penv pull is for a host that needs a file on disk. Connect your CI has the wrapped step.
