使用 docker 在 gitea 上 ssh

Question

我刚刚在 Linux mint 19 上使用 docker 安装了 gitea，我使用 /data 和旧的 gitea 安装，所以我有一个填充数据库和存储库。当我访问网络时，它似乎可以正常工作。

问题在于使用 SSH：

➜  /tmp sudo git clone git@gitealocal:felipe/test.git
Cloning into 'test'...
ssh: connect to host gitealocal port 22: Connection refused
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.


➜  /tmp ssh -vT gitealocal
OpenSSH_7.6p1 Ubuntu-4ubuntu0.1, OpenSSL 1.0.2n  7 Dec 2017

我检查了目录和文件/var/lib/gitea/ssh 的权限，但它似乎是正确的。 drwx------ 和 -rw-------

启动docker容器时需要暴露ssh端口22，试试：

docker run --expose 22 ...

或者甚至更好地将EXPOSE 22 添加到 Dockerfile 并按照official docs 修复 SSH 登录：

FROM ubuntu:16.04

RUN apt-get update && apt-get install -y openssh-server
RUN mkdir /var/run/sshd
RUN echo 'root:screencast' | chpasswd
RUN sed -i 's/PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config

# SSH login fix. Otherwise user is kicked off after login
RUN sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd

ENV NOTVISIBLE "in users profile"
RUN echo "export VISIBLE=now" >> /etc/profile

EXPOSE 22
CMD ["/usr/sbin/sshd", "-D"]
