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 top-level config in your Landofile.

Supported versions

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: go:1.13.9

But make sure you use one of the available patch tags for the underlying image we are using.

Configuration

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.

Also note that options in addition to the build steps and overrides that are available to every service are shown below:

services:
  myservice:
    type: go:1.13
    ssl: false
    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 go commands against).

If you want to actually launch a go application, consider setting the command to something as shown below:

services:
  myservice:
    type: go
    command: run /app/my-server.go

Using SSL

Also note that ssl: true will only generate certs in the default locations and expose port 443. It is up to the user to use the certs and secure port correctly in their application like as in the go snippet below:

// Starting HTTPS server
go func() {
  log.Printf("Staring HTTPS service on :443")
  if err := http.ListenAndServeTLS(":443", "/certs/cert.crt", "/certs/cert.key", nil); err != nil {
    // Not important for this example
  }
}()
