Ruby (opens new window) A dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.
# Supported versions
- 2.6 (opens new window)
- 2.5 (opens new window) (default)
- 2.4 (opens new window)
- 2.3 (opens new window)
# Legacy versions
You can still run these versions with Lando but for all intents and purposes they should be considered deprecated (e.g. YMMV and do not expect a ton of support if you have an issue).
# Patch versions
Not officially supported!
While we allow users to specify patch versions for this service, they are not officially supported, so if you use one, YMMV.
To use a patch version, you can do something as shown below:
services: myservice: type: ruby:2.5.3
But make sure you use one of the available patch tags (opens new window) for the underlying image we are using.
Here are the configuration options, set to the default values, for this service. If you are unsure about where this goes or what this means, we highly recommend scanning the services documentation to get a good handle on how the magicks work.
services: myservice: type: ruby:2.5 port: 80 command: tail -f /dev/null
# Specifying a command
Note that if you do not define a
command for this service, it will effectively be a "cli" container (e.g. it will not serve or run an application by default but will be available to run
ruby commands against).
If you want to actually launch a
ruby application, consider setting the
command to something as shown below:
services: myservice: type: ruby command: ruby /app/my-server.rb
# Setting a port
While we assume your
ruby service is running on port
80, we recognize that many
ruby apps also run on port
8080 or otherwise. You can easily change our default to match whatever your app needs.
services: myservice: type: ruby port: 8080
# Path Considerations
Lando will set the
PATH hierarchy for this service as follows:
[ '/usr/local/sbin', '/usr/local/bin', '/usr/local/bundle/bin', '/usr/sbin', '/usr/bin', '/sbin', '/bin', ]
This is useful to note if you are not using absolute paths in any tooling routes and are getting the unexpected version of a particular utility.
