在Jenkins Docker实例上找不到节点

Question

I am running Jenkins as a docker container, and have installed the NodeJS plugin and followed thoroughly the setup instructions. When I try to run a script using node , I get the following error:

/tmp/jenkins9123978873441132802.sh: line 1: node: not found
Build step 'Execute shell' marked build as failure
Finished: FAILURE

I checked the docker volume, the node bin is where it should be and is executable is there and it works fine when I run it from my host server:

user@server:/data/jenkins/tools/jenkins.plugins.nodejs.tools.NodeJSInstallation/latest/bin$ ./node --version
v9.2.0

I modified my build script to explore a bit further the problem:

echo $PATH

cd /var/jenkins_home/tools/jenkins.plugins.nodejs.tools.NodeJSInstallation/latest/bin
ls -all
./node --version

node --version
npm --version

and look how strange this is:

The node executable is present, and it's executable ( +x ). The path is correctly set, but the build still fails.

Answer 1

This is because the path to the node binary

/data/jenkins/tools/jenkins.plugins.nodejs.tools.NodeJSInstallation/latest/bin

Does not exist on your shell path.

You should edit Jenkins' variables to adjust your PATH.
