git install fails in Dockerfile
提问by dingo_d
I'm trying to pull the repository I'm working on while doing a docker build, so I followed this tutorialso I added in my Dockerfile
我正在尝试在进行 docker build 时拉出我正在处理的存储库，因此我遵循了本教程，因此我添加了Dockerfile
# this is our first build stage, it will not persist in the final image
FROM ubuntu as intermediate
# install git
RUN apt-get update \
apt-get upgrade \
apt-get install git
# add credentials on build
RUN mkdir ~/.ssh && ln -s /run/secrets/host_ssh_key ~/.ssh/id_rsa
# make sure your domain is accepted
RUN touch /root/.ssh/known_hosts
RUN ssh-keyscan github.org >> /root/.ssh/known_hosts
RUN git clone [email protected]:my-repo/myproject.git
FROM ubuntu
# copy the repository form the previous image
COPY --from=intermediate /your-repo /srv/your-repo
In my docker-compose.ymlI added
在我的docker-compose.yml我添加
secrets:
host_ssh_key:
file: ~/.ssh/id_rsa
And I'm adding
我正在添加
secrets:
- host_ssh_key
In one of the service.
在其中一项服务。
Since this is only for my local use (I don't plan on deploying or using this for the production, I just want to test it out) it's fine to use it this way - if it'll work because currently the build fails at the git install stage with error
由于这仅适用于我的本地使用（我不打算部署或将其用于生产，我只想对其进行测试）以这种方式使用它很好 - 如果它可以工作，因为当前构建失败出现错误的 git install 阶段
E: The update command takes no arguments
ERROR: Service 'web' failed to build: The command '/bin/sh -c apt-get update apt-get upgrade apt-get install git' returned a non-zero code: 100
E：更新命令不带参数
错误：服务“web”无法构建：命令“/bin/sh -c apt-get update apt-get upgrade apt-get install git”返回非零代码：100
What am I missing?
我错过了什么？

You are overanalyzing this. It's just a simple typo. Should be:
你过度分析了这一点。这只是一个简单的错字。应该：
RUN apt-get update && \
apt-get upgrade -y && \
apt-get install -y git
Those are 3 separate commands.
这些是 3 个单独的命令。

Some thoughts:
一些想法：
- Replace
apt-get install gitwithapt-get install --assume-yes git. Without the--assume-yesit will prompt you for confirmation, which you are unable to give and it will be smart enough to figure that out and assume you meant "NO".
- Replace
- You added the ssh key, but did you confirm it was
0600. I would just copy it and specificallychmod 0600 ~/.ssh/id_rsato be sure.
- You added the ssh key, but did you confirm it was
- 替换
apt-get install git为apt-get install --assume-yes git。如果没有--assume-yes它，它会提示您进行确认，而您无法给出确认，并且它会很聪明地弄清楚并假设您的意思是“不”。
- 替换
- 您添加了 ssh 密钥，但您确认它是
0600. 我只是复制它，特别是chmod 0600 ~/.ssh/id_rsa为了确定。
- 您添加了 ssh 密钥，但您确认它是
Overall, your Dockerfile looks very clever and I got some fresh ideas from reading it.
总的来说，你的 Dockerfile 看起来非常聪明，我从阅读中得到了一些新的想法。

For those working with alpineimages, RUN apk add --no-cache gitdid the trick for me.
对于那些处理alpine图像的人，RUN apk add --no-cache git对我有用。
