Create Your First Pipeline Configuration
Before you can start running containers you must tell Gofer what you want to run. To do this we create what is called a pipeline configuration.
The creation of this pipeline configuration is very easy and can be done in either Golang or Rust. This allows you to use a fully-featured programming language to organize your pipelines, instead of dealing with YAML mess.
Let's Go!
As an example, let's just copy a pipeline that has been given to us already. We'll use Go as our language, which means you'll need to install it if you don't have it. The Gofer repository gives us a simple pipeline that we can copy and use.
Let's first create a folder where we'll put our pipeline:
mkdir /tmp/simple_pipeline
Then let's copy the Gofer provided pipeline's main file into the correct place:
cd /tmp/simple_pipeline
wget https://raw.githubusercontent.com/clintjedwards/gofer/main/examplePipelines/go/simple/main.go
This should create a main.go file inside our /tmp/simple_pipeline directory.
Lastly, let's initialize the new Golang program:
To complete our Go program we simply have to initialize it with the go mod command.
go mod init test/simple_pipeline
go mod tidy
The pipeline we generated above gives you a very simple pipeline with a few pre-prepared testing docker containers. You should be able to view it using your favorite IDE.
The configuration itself is very simple. Essentially a pipeline contains of a few parts:
> Some basic attributes so we know what to call it and how to document it.
err := sdk.NewPipeline("simple", "Simple Pipeline").
Description("This pipeline shows off a very simple Gofer pipeline that simply pulls in " +
...
> The containers we want to run are defined through tasks.
...
sdk.NewTask("simple_task", "ubuntu:latest").
Description("This task simply prints our hello-world message and exits!").
Command("echo", "Hello from Gofer!").Variable("test", "sample"),
