Execute npm and node using ansible

I am facing a challenge with the script execution on a machine that has zsh installed. Here is what I have set up:

Software Installed

# Install NVM
sudo curl https://raw.githubusercontent.com/creationix/nvm/v0.31.0/install.sh | bash
## Reload shell to start using nvm
. ~/.zshrc
. ~/.nvm/nvm.sh
nvm install 0.12

My next step is to connect to the instance and run an ansible-playbook which will execute the following script:

sh-script.sh

npm install aws-sdk


node create-queue.js $machine_name
node create-queue.js $machine_name

However, upon running the playbook, I encounter the following errors: line 28: npm: command not found -- line 32: node: command not found -- line 33: node: command not found.

Interestingly, when I SSH into the instance and directly run "node" or "npm", I receive the expected responses without any issues. The ansible-playbook structure is quite simple:

ansible

- hosts: tag_Name_TestInstance
  tasks:
    - name: Run Script
      shell: /home/ubuntu/sh-script.sh '{{ machine_name }}'
node.jsnpmansiblezsh

Answer №1

To overcome this challenge, I recommend including an extra bin path in the ansible environment.

  - name: Setup aws-sdk
    command: /opt/node/bin/npm "something"
    environment:
      PATH: "{{ ansible_env.PATH }}:/opt/node/bin"

Alternatively, you can utilize the built-in ansible npm function.

   description: Install node.js package "aws-sdk".
  - npm: name=aws-sdk path=/app/location
    environment:
      PATH: "{{ ansible_env.PATH }}:/opt/node/bin"

Include two additional tasks to execute the node js script for a better understanding of the process.

Best of luck!

Answer №2

One possible reason for this issue could be that npm and node are not included in your system's $PATH. In such cases, the shell module may default to using /bin/sh to execute commands.

To resolve this and run the script in zsh, consider including a shebang line with the path to your zsh installation. For example: !#/usr/local/bin/zsh
