I'm trying to install nvm like this:
FROM maven:3-jdk-8
RUN rm /bin/sh && ln -s /bin/bash /bin/sh
RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
RUN source ~/.nvm/nvm.sh
RUN nvm install 16
RUN nvm use 16
However I keep getting this error:
=> [internal] load build definition from Dockerfile 0.0s
=> => transferring dockerfile: 253B 0.0s
=> [internal] load .dockerignore 0.0s
=> => transferring context: 2B 0.0s

#7 0.128 /bin/sh: line 1: nvm: command not found
------
executor failed running [/bin/sh -c nvm install 16]: exit code: 127
I would expect NVM is accessible because I run this line:
RUN source ~/.nvm/nvm.sh
What am I doing wrong here? When I run this manually in my docker container it works.
CodePudding user response：
Each RUN statement is executed in its own shell, therefore the source command does not affect the subsequent shells.
To fix it, use a single RUN command:
FROM maven:3-jdk-8
RUN rm /bin/sh && ln -s /bin/bash /bin/sh
RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
RUN source ~/.nvm/nvm.sh && nvm install 16 && nvm use 16
CodePudding user response：
The source command will not have effect on the next RUN command.
You need to have all the nvm commands in the same layer like this:
RUN source ~/.nvm/nvm.sh && nvm install 16 && nvm use 16
Or, if you would like to do it manually, the source command should be adding env variables (you can view them using the env command).
