title: "K8S private gitlab registry using podman"
date: 2021-12-28
tags: ['kubernetes', 'linux', 'podman', 'gitlab', 'k3s]
---
This is based on [[https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/][Log in to Docker Hub]].
It is just a bit different to use podman
First we should take a look at podman-login man page:
#+BEGIN_SRC bash
man podman login
#+END_SRC
It will give some valueable information like the location of auth.json file.
Now we can login using podman:
#+BEGIN_SRC bash
podman login registry.gitlab.com
#+END_SRC
Then check the ~auth.json~ file located at
~${XDG_RUNTIME_DIR}/containers/auth.json~ (as described by the manual).
#+BEGIN_SRC bash
cat "${XDG_RUNTIME_DIR}/containers/auth.json"
#+END_SRC
It will print your auth config:
#+BEGIN_SRC json
{
"auths": {
"registry.gitlab.com": {
"auth": "..."
}
}
}
#+END_SRC
Now copy that file over to the server and register it in k8s with the following command:
#+BEGIN_SRC bash
kubectl create secret generic regcred \
--from-file=.dockerconfigjson=auth.json \
--type=kubernetes.io/dockerconfigjson
#+END_SRC
Once you have created you can list by ~kubectl get secret~:
#+BEGIN_SRC
NAME TYPE DATA AGE
regcred kubernetes.io/dockerconfigjson 1 53s
#+END_SRC
