在 Docker 容器内运行 git clone 时，请求的 URL 返回错误：502

Question

I have a simple bash script git clone https://x-token-auth:$REPOSITORY_OAUTH_ACCESS_TOKEN@bitbucket.org/danechitoaie/open-pipelines-test1.git $BUILD_DIR that I run in a Docker container and the problem is that sometimes git clone fails with following error message fatal: unable to access 'https://x-token-auth:$REPOSITORY_OAUTH_ACCESS_TOKEN@bitbucket.org/danechitoaie/open-pipelines-test1.git/': The requested URL returned error: 502

This happens randomly, so sometimes it works sometimes I get this error.

Any idea what could the problem be?

Answer 1

The 502 http response means "Bad gateway". So you have some kind of connection problem to the repository. I think the problem is not related to docker. Probably on the host machine containing your Docker containers you'll have the same behavior if you try the git clone to the repository. Test it if you can.

You said it happens randomly. Are you behind a proxy or something similar? That issue happens sometimes under that proxy scenario. If that is your case, remember to put ENV var in your Dockerfiles with the proxy settings:

ENV http_proxy http://x.x.x.x:xxxx
ENV https_proxy https://x.x.x.x:xxxx

Answer 2

自昨天以来，我还从 bitbucket 中收到随机 502 错误，因此我认为 bitbucket 目前存在一些问题。

Answer 3

I got same issue in my company while clone a repository from GitHub, that may caused by your host machine network proxy configuration.

I don't know your network environment, but in my company, if you want visit Internet, you must config a proxy.

I edited .gitconfig by vim ~/.gitconfig , change to another http proxy server

........
[http]
        proxy = http://username:password@anotherproxy.mycompany.com:8080
[https]
        proxy = https://username:password@anotherproxy.mycompany.com:8080
        sslVerify = false
.....

and run git clone https://github.com/somesuer/someproject.git , it works
