tm

A CLI for knative

Installation

With a working Golang environment do:

go get github.com/triggermesh/tm

Or head to the GitHub release page and download a release.

Configuration

On TriggerMesh:

1. Request beta access to TriggerMesh cloud at https://triggermesh.com
2. Download your TriggerMesh configuration file by clicking on the download button in the upper right corner
3. Save the file as $HOME/.tm/config.json and you are ready to use the tm CLI

On your own knative cluster:

Assuming you have access to the Kubernetes API and have a working kubectl setup, tm should work out of the box.

Examples

Deploy service from Docker image

tm deploy service foo -f gcr.io/google-samples/hello-app:1.0 --wait

If you have Dockerfile for your service, you can use kaniko buildtemplate to deploy it

tm deploy service foobar \
    -f https://github.com/knative/docs \
    --build-template https://raw.githubusercontent.com/triggermesh/build-templates/master/kaniko/kaniko.yaml \
    --build-argument DIRECTORY=serving/samples/helloworld-go \
    --wait

or deploy service straight from Go source using Openfaas runtime

tm deploy service bar \
    -f https://github.com/golang/example \
    --build-template https://raw.githubusercontent.com/triggermesh/openfaas-runtime/master/go/openfaas-go-runtime.yaml \
    --build-argument DIRECTORY=hello \
    --wait

Moreover, for more complex deployments, tm CLI supports function definition parsing from YAML file and ability to combine multiple functions, runtimes and repositories

tm deploy -f https://github.com/tzununbekov/serverless

AWS Lambda

With triggermesh CLI you can easily deploy AWS Lambda functions on Kuberentes:

Prepare local source for Golang function

mkdir lambda
cd lambda
cat > main.go <<EOF
package main

import (
        "fmt"
        "context"
        "github.com/aws/aws-lambda-go/lambda"
)

type MyEvent struct {
        Name string `json:"name"`
}

func HandleRequest(ctx context.Context, name MyEvent) (string, error) {
        return fmt.Sprintf("Hello %s!", name.Name ), nil
}

func main() {
        lambda.Start(HandleRequest)
}
EOF

Deploy function using Knative lambda buildtemplate with Go runtime

tm deploy service go-lambda -f . --build-template https://raw.githubusercontent.com/triggermesh/knative-lambda-runtime/master/go-1.x/buildtemplate.yaml --wait

Lambda function available via http events

curl http://go-lambda.default.dev.triggermesh.io --data '{"Name": "Foo"}'
"Hello Foo!"

Here you can find more information about Knative lambda runtimes
