CircleCI

Jobs authenticate as the project they ran in.

What proves the identity

The token has to come from https://oidc.circleci.com/org/b9e4b4e1-0d3a-4a1e-9d2f-2f3a4b5c6d7e, and its oidc.circleci.com/project-id claim has to match the workload you named. penv compares that claim byte for byte, with no wildcards.

oidc.circleci.com/project-id is matched rather than sub, because this platform puts something per run in sub.

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

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:

penv names the identity for you, so the form never asks for one.

The snippet the console prints

steps:
  - run:
      name: Pull secrets
      command: |
        T=$(circleci run oidc get --claims '{"aud":"YOUR_WORKSPACE_ID"}')
        C=$(curl -sS "https://penv.cloud/api/v1/auth/oidc" \
          -H 'content-type: application/json' \
          -d "{\"token\":\"$T\"}" | jq -r .credential)
        PENV_TOKEN="$C" penv pull

The 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.
