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

我知道我可以做一些类似的工作

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

但我不想要。为什么？因为重点是创建一个docker容器，可以使用我的所有项目使用不同版本的python和node，并使用nvm use <version> && npm install文件直接从gitlab-ci运行.nvmrc到我的项目中

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

而且我不想将/bin/bash -c推送到我的makefile中，因为该项目将成为本地的docker

这是我的docker镜像，带有运行它的指令（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

我找不到合适的方法。

您可以使用/usr/bin/nvm在chmod +x /usr/bin/nvm中创建一个bash文件

#!/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 "$@"

然后

docker exec <container> nvm use

但它很棘手，我不能在我的执行官中添加其他指令，例如我不能同时使用docker exec <container> nvm use && npm install。

但我终于在gitlab-ci.yaml中直接解决了我的问题

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