Vault gitlab 17.x ce and jwt

Hello,

Has you now support for CI JWT variable has been remove … and i cannot manage to make the ID_TOKEN work,

here what i have in my gitlab (for the deployment )


deploy-sb:
  variables:
    VAULT_SERVER_URL: https://vault.coredmp.net
    VAULT_AUTH_PATH: jwt
    VAULT_AUTH_ROLE: reflexogest_front_elisa_dep_sandbox
    VAULT_NAMESPACE: ""
  id_tokens:
    VAULT_ID_TOKEN:
      aud: https://vault.coredmp.net

  script:
    - env
    - TAG=v$(cat VERSION)
    - echo "$VAULT_ID_TOKEN" > vault_token
    - /bin/sh scripts/deploy_env.sh "reflexogest_front_elisa" "ovh-01.coredmp.net" "/home/reflexogest_front_elisa_sandbox" "sandbox" $TAG
  environment:
    name: sandbox
    url: https://sanbox.reflexo-elizen.fr
    on_stop: stop-sb
  rules:
    - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH
      when: always
  artifacts:
    paths:
      - vault_token
    when: always
    expire_in: "30 days"

The congiruation of the Vault seems ok as i can get my secret using a generated token.

My problem is that i get this inside “vault_token” artefact :slight_smile:

I was suspected that it is base64 .so try to decode it :

fabrice@garfield-ubuntu:~/Downloads/artifacts (1)$ cat vault_token |base64 -d 
{"kid":"-99cmKOS5z-el1D_DSimqBD2fAvp-fZ_UkqRyRvuX-E","typ":"JWT","alg":"RS256"}base64: invalid input

After some reflexion … i see that there is a “.” inside the b64 … so separate in two part :

fabrice@garfield-ubuntu:~/Downloads/artifacts (1)$ cat vault_token | cut -d '.' -f 1 > first.b64
fabrice@garfield-ubuntu:~/Downloads/artifacts (1)$ cat vault_token | cut -d '.' -f 1 > second.b64

To eliminate error on b64, add some “=” at the end of each file ( two for the first on and one for the second ), and then i got this :

fabrice@garfield-ubuntu:~/Downloads/artifacts (1)$ cat first.b64 | base64 -d|jq
{
  "kid": "-99cmKOS5z-el1D_DSimqBD2fAvp-fZ_UkqRyRvuX-E",
  "typ": "JWT",
  "alg": "RS256"
}
fabrice@garfield-ubuntu:~/Downloads/artifacts (1)$ 

and

fabrice@garfield-ubuntu:~/Downloads/artifacts (1)$ cat second.b64 | base64 -d|jq

Well … this is not a Vault token … but the JWK wich should be used for getting the token …

Has anybody any explanation on what i am doing wrong ?

Thanks
