Application Management

You can use Ketch's provider for Pulumi to provide developers with an easy way to deploy applications across multiple Kubernetes clusters.

Deploying Applications

You can use the TypeScript example below as a base for creating applications:

import * as pulumi from "@pulumi/pulumi";
import * as ketch from "@shipa-corp/kpulumi";

const app = new ketch.App("a1", {
    app: {
        name: "a1",
        image: "docker.io/shipasoftware/bulletinboard:1.0",
        framework: "framework-name",
        cnames: ["a1.ketch.io", "a2.ketch.io"],
        ports: [8080, 8081],
        units: 1,
        processes: [
            {
                name: "web",
                cmds: ["docker-entrypoint.sh", "npm", "start"],
            }
        ],
        routingSettings: {
            weight: 100,
        }
    }});

export const appName = app.app.name;
