我有一个使用 ubuntu:21.04 的 Docker 镜像.当我通过 SSH 连接它时，我尝试安装 git using the official Git Ubuntu installation instructions但我收到一个错误:

root@c812b171354a:/home/ubuntu# sudo apt install git-all
bash: sudo: command not found

我很惊讶地看到 sudo不存在!所以我尝试不使用 sudo :

root@c812b171354a:/home/ubuntu# apt install git-all

E: Unable to locate package git-all

所以我问: 我可以运行什么命令来安装 git在 Dockerized Ubuntu 21.04 容器上？
更新
这是我的完整 Dockerfile:

FROM ubuntu:21.04

COPY keep-alive.sh /home/ubuntu/keep-alive.sh

# give keep-alive script permission to run
RUN ["chmod", "+x", "/home/ubuntu/keep-alive.sh"]

# install git
RUN apt update -y
RUN apt install -y gpgv2 git-all

CMD ["/bin/bash", "-c", "/home/ubuntu/keep-alive.sh"]

当我构建图像时:

docker build -t myorg/linux-worker .

我得到:

我还需要其他依赖项吗？

Answer 1

Ubuntu 镜像在软件包列表中没有任何内容，因此您需要 apt update然后 apt install git-all .
添加 -y如果您将它们放入 RUN 中的选项Dockerfile 中的命令。
