How to install Kompose on Ubuntu

Did you know that Kompose is a tool that helps users transition from Docker Compose to Kubernetes manifests?

In other words, it lets us take existing Docker Compose files that are used to define and run multi-container Docker applications, as well as automatically generate Kubernetes YAML files.

These Kubernetes manifests then deploy and manage our containerized applications on a Kubernetes cluster.

Let’s take a look at how to use Kompose on Ubuntu to migrate our Docker Compose files to Kubernetes:

1. First, we have to install Kompose by downloading the Kompose binary from the GitHub releases page.

   For example, we can download version 1.24.0:

   wget https://github.com/kubernetes/kompose/releases/download/v1.24.0/kompose-linux-amd64
2. Then, we have to rename the downloaded binary to “kompose” and move it to a directory in our PATH to make it executable:

   mv kompose-linux-amd64 kompose
chmod +x kompose
sudo mv kompose /usr/local/bin/
3. Next, we can verify that Kompose is installed correctly by running:

   kompose version
4. After Kompose is installed, we have to head to the directory with our Docker Compose file and run this command to convert it to Kubernetes manifests:

   kompose convert

   Then, Kompose will analyze our Docker Compose file and generate equivalent Kubernetes YAML files, including Pods, Services, Deployments, and ConfigMaps.
5. Then, we can opt to make manual adjustments to the generated YAML files to match our requirements or configurations.
6. Now, we can use the kubectl command to apply the generated YAML files to our Kubernetes cluster. Furthermore, remember to make sure the kubectl is configured to point to the desired Kubernetes cluster.

At the end of the day, Kompose simplifies migrating our Docker Compose-based applications to Kubernetes.
