我想创建一个基于Docker的Gitlab CI运行器,它从私有Docker Registry(v2)中为构建提取docker镜像。我不能让Gitlab Runner从本地注册表中提取图像,它试图从/v1
API中获取内容。我收到以下错误消息:
错误:构建失败:拉图像时出错:获取http://registry:5000/v1/repositories/maven/images:在127.0.1.1:53上拨打tcp:lookup注册表:没有这样的主机
这是一个最小的例子,使用docker-compose和网络浏览器。
我有以下docker-compose.yml
文件:
version: "2"
services:
gitlab:
image: gitlab/gitlab-ce
ports:
- "22:22"
- "8080:80"
links:
- registry:registry
gitlab_runner:
image: gitlab/gitlab-runner
volumes:
- /var/run/docker.sock:/var/run/docker.sock
links:
- registry:registry
- gitlab:gitlab
registry:
image: registry:2
在第一次Gitlab登录后,我将跑步者注册到Gitlab实例中:
root@130d08732613:/# gitlab-runner register
Running in system-mode.
Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/ci):
http://192.168.61.237:8080/ci
Please enter the gitlab-ci token for this runner:
tE_1RKnwkfj2HfHCcrZW
Please enter the gitlab-ci description for this runner:
[130d08732613]: docker
Please enter the gitlab-ci tags for this runner (comma separated):
Registering runner... succeeded runner=tE_1RKnw
Please enter the executor: docker-ssh+machine, docker, docker-ssh, parallels, shell, ssh, virtualbox, docker+machine:
docker
Please enter the default Docker image (eg. ruby:2.1):
maven:latest
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!
在此之后,我在Gitlab实例中看到了Gitlab运行器:
在此之后,我将一个简单的maven图像推送到我新创建的Docker存储库:
vilmosnagy@vnagy-dell:~/$ docker tag maven:3-jdk-7 172.19.0.2:5000/maven:3-jdk7
vilmosnagy@vnagy-dell:~/$ docker push 172.19.0.2:5000/maven:3-jdk7
The push refers to a repository [172.19.0.2:5000/maven]

(我从172.19.0.2
命令的输出中获得了docker inspect
IP地址
在此之后,我在Gitlab中创建了一个测试项目并添加了一个简单的.gitlab-ci.yml
文件:
image: registry:5000/maven:3-jdk-7
stages:
- build
- test
- analyze
maven_build:
stage: build
script:
- "mvn -version"
在构建之后,Gitlab会在帖子的开头给出错误。
如果我进入正在运行的gitlab-runner容器,我可以访问给定URL下的注册表:
vilmosnagy@vnagy-dell:~/$ docker exec -it comptest_gitlab_runner_1 bash
root@c0c5cebcc06f:/# curl http://registry:5000/v2/maven/tags/list
{"name":"maven","tags":["3-jdk7"]}
root@c0c5cebcc06f:/# exit
exit
vilmosnagy@vnagy-dell:~/$
但错误仍然相同:
您是否知道如何强制gitlab-runner使用私有注册表的v2 api?
答案 0 :(得分:5)
较新的Gitlab和Gitlan Runners支持此功能,请参阅:https://docs.gitlab.com/runner/configuration/advanced-configuration.html#using-a-private-container-registry
在较旧的Gitlab上我通过将身份验证密钥复制到~/.docker/config.json
{
"auths": {
"my.docker.registry.url": {
"auth": "dmlsbW9zLm5hZ3k6VGZWNTM2WmhC"
}
}
}
我已从我的计算机登录此容器,并将此身份验证密钥复制到Gitlab Runner的docker容器中。
答案 1 :(得分:0)
你在Gitlab上运行什么版本的docker? 此外,对于v2注册表,您必须使用命令行开关明确允许不安全的注册表,或使用证书保护您的注册表。
否则,如果获得安全性异常,Docker将回退到v1注册表。
