kompose VS Docker Compose

Install Kompose - a conversion tool that allows you to convert your Docker Compose code to Kubernetes configuration files Run kompose convert in the same directory as your docker-compose.yml to generate the config files for your Kubernetes cluster

Kubernetes (via kompose)

As stated on their homepage, with Kompose, you can now push the same file to a production container orchestrator!. The tool definitely covers a wide range of Kubernetes features, among which these are meaningless locally but crucial for kubernetes :

K3s is a small, open source, no nonsense, distribution of Kubernetes. I think you'll find it just as easy to setup as Swarm. The challenge will be that Kubernetes has an entirely different API compared to Docker/Docker Compose. This can be mitigated by a tool called kompose, but using this will limit what you can do on Kubernetes.

Although I recently moved my own services from docker compose to kubernetes using https://kompose.io/ and now the only thing I run with docker compose, currently, is my private docker registry but everything including in kube, are always in their own folders.

I haven't run into the need to do that, but there is the Kompose project that exists to help with the conversion (https://kompose.io/)!

Compose claims to do that. https://kompose.io and https://kubernetes.io/docs/tasks/configure-pod-container/translate-compose-kubernetes/

curl -fsSL https://get.docker.com -o get-docker.sh sudo sh get-docker.sh # Install docker compose sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose # Apply executable permissions to the binary sudo chmod +x /usr/local/bin/docker-compose # Run Project docker-compose up -d

Docker,

This foundation now opens the door to even more powerful concepts. You can explore more advanced concepts such as container networking, streamlining the management of complex applications with Docker Compose, and how to make your application data persistent using volumes.

In many projects that are containerized, especially in cases where development is also done locally with docker-compose, teams often have two Dockerfiles, 1 for Development, the other for Production. If you happen to have multiple environments like pre-prod, staging and so on, some teams could have different Dockerfiles for these environments.

sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

You can also use Docker Compose to deploy the cluster, without having to write all the previous commands.

[ec2-user]$ sudo yum update -y [ec2-user]$ sudo yum install -y docker [ec2-user]$ sudo service docker start [ec2-user]$ sudo curl -L https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose [ec2-user]$ sudo chmod +x /usr/local/bin/docker-compose [ec2-user]$ docker --version Docker version 20.10.23, build 7155243 [ec2-user]$ docker-compose --version Docker Compose version v2.18.1
