SOLVED - Kubernetes can't pull private image from docker-CodePudding

I hope somebody can help me. I'm trying to pull a private docker image with no success. I already tried some solutions that I found, but without success.

Docker, Gitlab, Gitlab-Runner, Kubernetes all run on the same server

Insecure Registry

$ sudo cat /etc/docker/daemon.json
{ "insecure-registries":["10.0.10.20:5555"]}

Config.json

$ cat .docker/config.json
{
        "auths": {
                "10.0.10.20:5555": {
                        "auth": "NDUwNjkwNDcwODoxMjM0NTZzIQ=="
                },
                "https://index.docker.io/v1/": {
                        "auth": "NDUwNjkwNDcwODpGcGZHMXQyMDIyQCE="
                }
        }
}

Secret

$ kubectl create secret generic regcred \
    --from-file=.dockerconfigjson=~/.docker/config.json \
    --type=kubernetes.io/dockerconfigjson

I'm trying to create a Kubernetes pod from a private docker image. However, I get the following error:

When I pull the image directly in docker, no problem occurs even with the secret

Pull image

Can someone help me?

EDIT - SOLVED I solved the problem by creating a file /etc/containerd/config.toml

# Config file is parsed as version 1 by default.
# To use the long form of plugin names set "version = 2"
[plugins.cri.registry.mirrors]
  [plugins.cri.registry.mirrors."10.0.10.20:5555"]
    endpoint = ["http://10.0.10.20:5555"]

CodePudding user response：

Solved

First, you need to create a file in /etc/containerd/config.toml

# Config file is parsed as version 1 by default.
# To use the long form of plugin names set "version = 2"
[plugins.cri.registry.mirrors]
  [plugins.cri.registry.mirrors."10.0.10.20:5555"]
    endpoint = ["http://10.0.10.20:5555"]

Second, restart contained

$ systemctl restart containerd
