<p>I try to integrate vault and <em>gitlab</em>.</p>
<p><em>Vault</em> side is ok , and I try to locate vault in our <em>gitlab-ci.yaml</em> but I confused something.</p>
<p>Where is the location of <em>vault</em> in <em>yaml</em> ?</p>
<p>We use <em>gitlab ee</em> (community).</p>
<p>Our <em>yaml</em>:</p>

<p>If you've not already done so, you first need to configure vault for jwt authentication.</p>
<pre><code>vault auth enable -path=jwt/gitlab jwt
</code></pre>
<p>Then configure the new jwt auth with a token validation endpoint that references your gitlab instance.</p>
<pre><code>vault write auth/jwt/config \
jwks_url=&quot;https://gitlab.example.com/-/jwks&quot; \
bound_issuer=&quot;gitlab.example.com&quot;
</code></pre>
<p>Now in your gitlab-ci.yml, login to vault.</p>
<pre><code>- export VAULT_ADDR=&quot;https://gitlab.example.com&quot;
- export VAULT_TOKEN=&quot;$(vault write -field=token auth/jwt/gitlab/login role=SOME_ROLE_NAME jwt=$CI_JOB_JWT)&quot;
</code></pre>
<p>Next in your gitlab-ci.yml, retrieve the secret.</p>
<pre><code>- export EXAMPLE_SECRET=&quot;$(vault kv get -field=EXAMPLE_SECRET_KEY kv-v2/example/secret/path)&quot;
</code></pre>
<p>This is all covered in more detail in the official GitLab docs <a href="https://docs.gitlab.com/ee/ci/examples/authenticating-with-hashicorp-vault/" rel="nofollow noreferrer">here</a></p>
