如何在 Docker 镜像 python:3 上安装 yq?

t29*_*ato 3 debian docker yq

我想做的事

我想安装yq并编辑 Docker 容器上的一些 yaml 文件。

Dockerfile

FROM python:3
RUN apt-get update

RUN apt-key adv --keyserver keyserver.ubuntu.com --keyserver-option http-proxy=http://xxxxxx.com:9999 --recv-keys CC86BB64
RUN apt-get install -y software-properties-common
RUN add-apt-repository ppa:rmescandon/yq
RUN apt update
RUN apt install yq -y

问题

我该如何修复它?

长话短说

该映像的 Linux 发行版yq上不提供PPA 。 更改您的 Dockerfile 以直接下载二进制文件:python:3

FROM python:3

RUN apt-get update
RUN apt-get install -y wget

# Latest on https://launchpad.net/~rmescandon/+archive/ubuntu/yq is 4.9.6
ARG VERSION=v4.9.6
ARG BINARY=yq_linux_386
RUN wget https://github.com/mikefarah/yq/releases/download/${VERSION}/${BINARY} -O /usr/bin/yq \ 
    && chmod +x /usr/bin/yq
Run Code Online (Sandbox Code Playgroud)

解释

上述安装说明yq需要基于 Ubuntu 的映像,但python:3Docker 映像基于 Debian 10 / Buster(截至撰写本答案时):

Dockerfile python:3= python:3.9=python:3.9.6

FROM buildpack-deps:buster
Run Code Online (Sandbox Code Playgroud)
FROM python:3

RUN apt-get update
RUN apt-get install -y wget

# Latest on https://launchpad.net/~rmescandon/+archive/ubuntu/yq is 4.9.6
ARG VERSION=v4.9.6
ARG BINARY=yq_linux_386
RUN wget https://github.com/mikefarah/yq/releases/download/${VERSION}/${BINARY} -O /usr/bin/yq \ 
    && chmod +x /usr/bin/yq
Run Code Online (Sandbox Code Playgroud)

错误

E:存储库“http://ppa.launchpad.net/rmescandon/yq/ubuntu impish Release”没有发布文件。

意味着该软件包ppa:rmescandon/yq 不支持您的发行版您可以从http://ppa.launchpad.net/rmescandon/yq/ubuntu检查支持的发行版:

ppa 的 dists 文件夹

解决方法是从源代码安装它或仅下载yq二进制文件本身。这是由 yq 支持的: https: //github.com/mikefarah/yq#wget

获取

使用 wget 下载预编译的二进制文件:

通过 tar.gz 压缩

wget https://github.com/mikefarah/yq/releases/download/${VERSION}/${BINARY}.tar.gz -O - | tar xz && mv ${BINARY} /usr/bin/yq
Run Code Online (Sandbox Code Playgroud)

纯二进制

wget https://github.com/mikefarah/yq/releases/download/${VERSION}/${BINARY} -O /usr/bin/yq && chmod +x /usr/bin/yq
Run Code Online (Sandbox Code Playgroud)

例如,VERSION=v4.2.0 和 BINARY=yq_linux_amd64

从yq 的版本页面中选择一个特定版本(最好与 PPA 中为 Ubuntu 分发的版本之一匹配)并将 Dockerfile 修改为:
