Docker未运行...失败

时间:2018-09-19 09:26:44

标签: docker service dockerfile

我正在运行以下命令:

docker run --name myjenkins -u root -d -p 8080:8080 -p 50000:50000 -v jenkins-data:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock --privileged vaish

docker exec -it myjenkins vaish

service docker start

service docker status

输出为[FAIL] Docker未运行...失败!

注意:我已经通过dockerfile安装了docker 注意:我的应用程序是一组Docker容器

当我在主机上检查服务docker状态时,它处于活动状态(正在运行),但问题出在容器内部!

Dockerfile:

RUN usermod -aG docker jenkins

USER jenkins
COPY Jenkinsfile /var/jenkins_home/workspace/pipelineDemo@script
CMD [ "npm", "start" ]

当我在jenkins docker容器中没有docker并且运行npm run install时,我会收到以下日志:为了避免这些错误,我不得不在我的jenkins docker容器中安装docker和docker compose

> /var/jenkins_home/workspace/pipelineDemo@script
> node tasks/down.js

✖ Command failed: docker-compose kill
/bin/sh: 1: docker-compose: not found


>/var/jenkins_home/workspace/pipelineDemo@script
> node tasks/build.js

 ✔ bundle admin
 ✔ bundle front-end
 ✖ build admin
   → /bin/sh: 1: docker: not found
 ✖ build bank-accounts
   → /bin/sh: 1: docker: not found

注意:在我的主机上,docker已安装了npm i,npm运行安装命令

我有同样的问题。我找到了解决方法here

启动Jenkins容器时,请使用-v将主机的docker.sock移至该容器:

docker run -v /var/run/docker.sock:/var/run/docker.sock ...

在Jenkins由用户jenkins运行时,您运行根目录也可能是一个问题。我希望会有一个不同的错误。

这是我的Jenkinsfile(我没有安装docker-compose

FROM jenkins/jenkins

USER root

RUN apt update && apt install -y apt-transport-https ca-certificates curl gnupg2 software-properties-common
RUN curl -fsSL https://download.docker.com/linux/debian/gpg | apt-key add -
RUN apt-key fingerprint 0EBFCD88
RUN add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
RUN apt update && apt install -y docker-ce
RUN usermod -aG docker jenkins

USER jenkins

我用以下容器启动容器

docker run --name mycustomjenkins \
  -p 8080:8080 -p 50000:50000 \
  -v jenkins_home:/var/jenkins_home \
  -v /var/run/docker.sock:/var/run/docker.sock <IMAGE-ID>

这样,我就可以在Jenkins中使用Docker代理了。

我无法使myjenkins容器独立,因此我在docker run命令中使用--net = hots运行它,因此它至少可以正常工作。不是我想要的,但最终还是这样。
