我正在尝试构建 docker 映像并在 Jenkins 管道内使用 docker-compose 启动容器。
我有一个适用于 Jenkins 的自定义 docker 映像，其中我使用开箱即用的 Jenkins 映像并安装 Docker CE 和 docker compose。
Docker 文件：
FROM jenkins/jenkins:2.159
USER root
# create dir to save jenkins log files
RUN mkdir /var/log/jenkins
RUN chown -R jenkins:jenkins /var/log/jenkins

RUN curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
RUN chmod +x /usr/local/bin/docker-compose
RUN docker-compose --version
USER jenkins
RUN id -nG
#tell jenkins to use the created folder to store logs
我用构建这个图像docker-compose build使用这个 docker-compose 文件：
version: '3'
volumes:
jenkins-log:
jenkins-data:
networks:
jenkins-net:
services:
master:
build: ./jenkins-master
ports:
- "50000:50000"
volumes:
- jenkins-log:/var/log/jenkins
- jenkins-data:/var/jenkins_home
- /var/run/docker.sock:/var/run/docker.sock
networks:
- jenkins-net
nginx:
build: ./jenkins-nginx
ports:
- "80:80"
networks:
- jenkins-net
并开始它docker-compose -p jenkins up -d
这会启动 Jenkins 并且目前工作正常。
然后我创建一个使用以下 Jenkinsfile 的管道作业：
node {
stage('Build Docker Image') {
sh '''
cd env-ci/
docker-compose --version
docker --version
docker-compose build
'''
}
}
当我运行此管道时，出现以下错误：
+ cd env-ci/
+ docker-compose --version
docker-compose version 1.22.0, build f46880fe
+ docker --version
Docker version 18.09.1, build 4c52b90
+ docker-compose build
Couldn't connect to Docker daemon at http+docker://localhost - is it running?
If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
当我尝试跑步时docker info管道内：
node {
stage('Build Docker Image') {
sh '''
cd env-ci/
docker-compose --version
docker --version
docker info
'''
}
}
我收到以下错误：
+ cd env-ci/
+ docker-compose --version
docker-compose version 1.22.0, build f46880fe
+ docker --version
Docker version 18.09.1, build 4c52b90
+ docker info
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.39/info: dial unix /var/run/docker.sock: connect: permission denied
我目前不知道问题是什么或如何解决它。
Jenkins 管道以用户身份运行jenkins并且该用户被添加到docker组中。所以权限should没事的？！
有谁知道可能出了什么问题吗？
谢谢你！
