问题描述
我正在使用 docker + machine 运行我的 gitlab ci/cd作业.
I am using docker+machine to run my gitlab ci/cd jobs.
所以我的 .gitlab-ci.yml 如下所示:
stages:
- RUN_TESTS
image:
name: docker:stable
services:
- name: docker:dind
variables:
DOCKER_HOST: tcp://docker:2375/
DOCKER_DRIVER: overlay2
DOCKER_TLS_CERTDIR: ""
build-docker:
stage: RUN_TESTS
script:
- echo "Running the tests..."
- docker build -t run-tests .
对于上面设置为 service 块的 docker:dind 映像，这完全可以正常工作.
This works totally fine with docker:dind image set as the service block as shown above.
现在这是有趣的部分，我需要在 docker:dind 图像内添加一些其他软件包.所以我写了 Dockerfile 如下:
Now here comes the fun part, I need some other packages inside the docker:dind image. So I wrote the Dockerfile as below:
FROM docker:dind
RUN apk update
ENV PYTHONUNBUFFERED=1
RUN apk add --update --no-cache python3 && ln -sf python3 /usr/bin/python
RUN python3 -m ensurepip
RUN pip3 install --no-cache --upgrade pip setuptools
RUN apk add groff
RUN pip3 install awscli
RUN apk --purge -v del py-pip
RUN rm /var/cache/apk/*
因此，我构建了上面的图像并将其推送到我的dockerhub中.
So, I built the above image and pushed it into my dockerhub.
截至目前，一切都很棒.图像成功构建并成功推送.
As of now, everything is cool. Image built successfully and pushed successfully.
然后我将 .gitlab-ci.yml 中的 services 更改为新图像，如下所示:
And then I changed the services in the .gitlab-ci.yml to my new images as below:
services:
- name: 199508/dind-new:latest
我运行了管道，并在下面得到了错误.
And I ran the pipeline and I get the error below.
我在下面遇到的这个错误很奇怪:
This error I am getting below is strange:
我所做的唯一更改是在上面的 Dockerfile 中安装了一些应用程序/依赖项，但是为什么它不起作用?当我使用 docker:dind 起作用时，以及使用相同的 docker:dind 基本映像创建新的 Dockerfile 时，为什么会这样呢?不行吗?
The only change I did was installing some applications/dependencies in the above Dockerfile but why it is not working? How come when I use docker:dind it is working and when I created a new Dockerfile with the same docker:dind base image and it doesn't work?
有人可以帮我吗?
推荐答案
实际上我昨天才遇到这个问题最主要的是切换到Docker映像版本就您而言，Dockerfile中的情况不像这里
Actually I just run into this problem yesterdayThe main thing is to switch to docker image versionIn Your case in the Dockerfile not like here
FROM docker:18.09
并更改端口:注释掉的行是曾经对我不起作用的行.
And change the port:The lines commented out are the once the didn't work for me.
image: 199508/dind-new:v5
services:
# - docker:19.03.12-dind
- docker:18.09-dind
variables:
# Use TLS https://docs.gitlab.com/ee/ci/docker/using_docker_build.html#tls-enabled
DOCKER_HOST: tcp://docker:2375/
# DOCKER_HOST: tcp://docker:2376
# DOCKER_TLS_CERTDIR: "/certs"
DOCKER_TLS_CERTDIR: ""
CONTAINER_TEST_IMAGE: $CI_REGISTRY_IMAGE:$CI_COMMIT_REF_SLUG
CONTAINER_RELEASE_IMAGE: $CI_REGISTRY_IMAGE:latest
DOCKER_DRIVER: overlay2
