docker - 使用 docker exec 运行 nvm

Question

我想用 docker exec 运行 nvm

就像是

docker run -d <image>
docker exec <container> nvm use v6.13.0 && npm install

但我有一个错误

OCI runtime exec failed: exec failed: container_linux.go:296: starting container process caused "exec: \"nvm\": executable file not found in $PATH": unknown

我知道我可以做类似的事情

docker exec <container> /bin/bash -c 'source "$NVM_DIR"/nvm.sh && nvm use v6.13.0'

但我不想。为什么 ？因为重点是创建一个可用于我所有项目的 docker 容器，使用不同版本的 python 和 node 并运行 nvm use <version> && npm install直接从 gitlab-ci 使用 .nvmrc文件到我的项目

我的 gitlab-cy.yml 运行一个 makefile，它基本上运行 nvm use 和 npm install

image: cracky5457/nvm-pyenv-yarn

stages:
  - install
  - test

variables:
  GITLAB_CACHING: "true"

cache:
  paths:
    - pip-cache/
  key: "python_2.7"

installing:
  stage: install
  script:
    - make install
  artifacts:
    paths:
      - venv/
      - node_modules/
    expire_in: 1 hour
  tags:
    - docker-runner

我不想推 /bin/bash -c进入我的 makefile，因为该项目将在本地依赖于 docker

这是我的 docker 镜像以及运行它的说明(你必须创建一个文件 base_dependencies.txt, node-versions.txt, python-versions.txt )或者你可以只是 docker pull cracky5457/nvm-pyenv-yarn
https://hub.docker.com/r/cracky5457/nvm-pyenv-yarn/

我没有找到合适的方法。

您可以在 /usr/bin/nvm 中创建一个 bash 文件与 chmod +x /usr/bin/nvm

#!/bin/bash

export NVM_DIR="/usr/local/nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

nvm "$@"

进而

docker exec <container> nvm use

但这很棘手，我无法在我的 exec 中添加其他指令，例如我不能 docker exec <container> nvm use && npm install同时。

但我终于在 gitlab-ci.yaml 中直接解决了我的问题使用

 $(NVM_DIR)/nvm.sh && nvm use && npm install
