What language/platform-specific examples/templates would you like to see next?

[jpadams]

We have a repo to hold Dagger examples including what we're calling "templates": small, ready-to-run examples of Dagger being used for a specific platform or language (think Node.js, Java, Python, etc). The templates are currently mostly "build" examples, but that could be expanded to simple "deploy" or "test" scenarios as well.

https://github.com/dagger/examples

If there is an example template that you'd like to see, please create a comment below. Ideally, one comment per template type so folks can upvote ones they like. Or feel free to vote with your keyboard and make a PR :)

Thanks!

I would like to see some examples of deploying a node app to ECS Fargate.

[jpadams]

@jritsema do you have an example in the AWS docs/examples that would be a good first example to emulate?

Guessing it's:

• copy in source code
• build an image
• push to ECR
• then the harder parts :) ECS task definition in aws cli or CFT or Terraform or Pulumi or ...

[nipuna-perera]

I would love to see some terraform examples. Like a lambda function deployment.

Templates

• building a maven project with .m2 cache
• pushing to ecr
• cloning another repository and executing helm manifest and commiting to git after pushing to ecr
• running terraform and waiting for user approval
• using buildkit on kubernetes

Ansible deployment to a Virtual Machine or network devices would be cool including ansible-lint and molecule role tests.

Docker build and push to container repository would be cool to have as an example

[tomiberes]

A "go-sdk" equivalent of docker build -t service/name . and docker run -d service/name.

[jpadams]

Support for running services like docker run -d is still under development. Stay tuned!

The docker build from a Dockerfile example works and is in the reference docs today here: https://pkg.go.dev/dagger.io/dagger#Container.Build:~:text=a%20Dockerfile%20build-,Example
Use docker login in your terminal before running to push to a registry that needs auth.

That example shows pulling the filesystem with the Dockerfile from a git repo, but you could read from the host filesystem as well like this:

My main.go:

package main

import (
	"context"
	"fmt"
	"os"

	"dagger.io/dagger"
)

func main() {
	ctx := context.Background()

	client, err := dagger.Connect(ctx, dagger.WithLogOutput(os.Stdout))
	if err != nil {
		fmt.Printf("Error connecting to Dagger Engine: %s", err)
		os.Exit(1)
	}

	defer client.Close()

	src := client.Host().Workdir()
	if err != nil {
		fmt.Printf("Error getting reference to host directory: %s", err)
		os.Exit(1)
	}
	_, err = client.Container().
		Build(src).
		Publish(ctx, "jeremyatdockerhub/gosdk-example:latest")

	if err != nil {
		fmt.Printf("Error creating and pushing container: %s", err)
		os.Exit(1)
	}
}

Dockerfile I used:

FROM alpine
CMD ["echo", "Hello World"]
