如何在bitnami/prometheus映像上安装bash？

Question

我试图使用肉桂/普罗米修斯容器，根据它的文档，它是基于没有shell的微型b容器映像的。为了调试目的，我想安装一个Bash。我注意到这可以直接在bitnami/minideb映像上工作，即下面的Dockerfile，

FROM bitnami/minideb:latest
RUN install_packages bash

成功构建：

> docker build -t prometheus .

但是，如果我使用bitnami/prometheus而不是bitnami/minideb，

FROM bitnami/prometheus:latest
RUN install_packages bash

构建它的尝试会导致错误，原因是缺少目录/var/lib/apt/lists/partial。

知道如何在bitnami/prometheus上安装Bash吗？

Answer 1

默认情况下，image bitnami/prometheus已经有bash了。您可以使用docker run -d bitnami/prometheus:latest运行图像bitnami/prometheus，并使用docker ps获取CONTAINER_ID，然后使用命令检查

docker exec -it CONTAINER_ID /bin/bash

如果要安装其他软件包，请在Dockerfile中使用以下命令

FROM bitnami/prometheus:latest
RUN apt install package_name
