Custom Install Script With Docksal

The full documentation for this can be found on my blog. Using Docksal for Local Web Development: How I'm integrating Node, Yarn, Jekyll, and Ruby It should be noted that this is more of an experiment than anything and I am just learning custom scripting using BASH / ZSH. No doubt, there might be something more efficient but I used this for learning and it does work as I needed to update a few Jekyll sites. (Eventually I might migrate them to Hugo, a platform on which this site is built.)


# Execute the whole script inside cli container
#: exec_target=cli

## Install RVM and target Ruby version
## Usage: 
## fin install

# Check for and install Node Version Manager
if ! (which nvm); then

  # Load NVM.
  [ -s "$NVM_DIR/" ] && \. "$NVM_DIR/"
  # Load NVM  bash_completion.
  [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"
  # Source / reload profiles.
  source ~/.bashrc
