Move2Kube automatically analyzes all the YAML files in the docker-compose directory and transforms and creates all artifacts required for deploying the application in Kubernetes using the transform command.
$ move2kube transform -s docker-compose
Note: This tutorial has been created with
v0.3.3-rc.2version of Move2Kube.
$ MOVE2KUBE_TAG='v0.3.3-rc.2' bash <(curl https://raw.githubusercontent.com/konveyor/move2kube/main/scripts/install.sh)
This tutorial shows how to migrate an application written for Docker Compose to run on Kubernetes using the two Docker Compose samples from the move2kube-demos repo.
Sample 1 is a web app with a single service using Nginx and a prebuilt image.
Sample 2 is more complicated. It is also a web app, but it has three services.
For the cache service use a prebuilt Redis image for this tutorial.
Below are the steps for migrating the second sample. The steps for the first sample are similar except that since it uses prebuilt images, skip the build and push the images portion.

Important: For most prompts, accept the default in this tutorial. However, some prompts to watch out for are:
redis service:. Select ClusterIP so the service port will not be exposed via the Ingress./ use that instead of /web.namespace here means the username on the target image registry and not the Kubernetes cluster namespace.localhost as the ingress host domain. If deploying to a Kubernetes cluster on IBM Cloud, then find the ingress subdomain on the cluster on IBM Cloud as shown here. Leave the TLS secret blank.$ move2kube transform
