go

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. You can easily add it to your Lando app by adding an entry to the services key in your app's .lando.yml.

Supported versions

Using patch versions

While Lando does not "officially" support specifying a patch version of this service you can try specifying one using overrides if you need to. This is not guaranteed to work so use at your own risk and take some care to make sure you are using a debian flavored patch version that also matches up with the major and minor versions of the service that we indicate above in "Supported versions".

Here are all the tags that are available for this service.

Here is an example of overriding the nginx service to use a patched version.

# The name of my app
name: patchversion

# Give me http://patchversion.lndo.site and https://patchversion.lndo.site
proxy:
  appserver:
    - patchversion.lndo.site

# Configure my services
services:

  # Create an nginx service called "appserver"
  appserver:

    # Set this to custom so we can override down the stream
    type: nginx:custom

    # SSL
    ssl: true

    # Override the image with the patch version
    # Note that this needs to be a correct namespace on the docker hub
    overrides:
      services:
        image: nginx:1.12.1

# Quick comamnd to check the nginx version
tooling:
  nginx:
    service: appserver

Example

# Go server example
name: go

# Give me http://go.lndo.site and https://go.lndo.site
proxy:
  appserver:
    - go.lndo.site

# Spin up services to run a basic go server
services:

  # Create a go instance
  appserver:

    # go version 1.8
    type: go:1.8

    # Optionally create certs in /certs that can be used by your application
    # to listen over https. Creates the following certs your app can use
    #
    #   - /certs/cert.key
    #   - /certs/cert.crt
    #   - /certs/cert.pem
    #
    # ssl: true

    # Optionally specify a command to run when you start your go service up.
    #
    # If you are using go as a server you are going to want to define this.
    # This can be either a string or array.
    #
    # If you are just spinning up a go container to run cli things
    # you can leave this blank and the container will boot up and stay on
    #
    command: go run /app/http1.go

    # Install some extra server packages
    # run_as_root:
    #  - "apt-get update -y"
    #  - "apt-get install vim -y"

    # Print a message just to demonstrate this
    # run:
    # - "cd $LANDO_MOUNT & echo 'Holla!'"

# Add some nice command routing
tooling:

  # Any go service with a defined command (aka not running in cli only mode)
  # Will also spin up a go cli container called `SERVICENAME_cli` (appserver_cli)
  # in this example.
  #
  # This will allow you to run things like `lando npm install` without needing
  # to `lando start` first. This is particularly needed for go based projects
  # since you almost always need to run `npm install` before you can boot up your
  # app successfully.
  go:
    service: appserver_cli

You will need to rebuild your app with lando rebuild to apply the changes to this file. You can check out the full code for this example over here.
