dockubeadt 0.2.4

Translate Docker compose and k8s manifests to a MiCADO ADT

Docker Compose and K8s manifests to (MiCADO) ADT

Translate a single or multi-part YAML file containing Kubernetes manifests or a Docker compose into a MiCADO ADT.

Requirements

• Python >= 3.6
• click
• ruamel.yaml

Usage

Install compose binary:

curl -L https://github.com/kubernetes/kompose/releases/download/v1.26.1/kompose-linux-amd64 -o kompose
chmod +x kompose
sudo mv ./kompose /usr/local/bin/kompose

Clone the repository:

git clone <repository> dockubeadt
cd dockubeadt

Install and run dockubeadt with pip:

pip3 install .
dockubeadt PATH/TO/FILENAME.YAML

Or skip the install and simply:

python3 -m dockubeadt PATH/TO/FILENAME.YAML

Generated output file will be saved to your current directory as adt-FILENAME.YAML

Things to note(Docker Compose)

• All the volume mounts in docker compose are by default converted to 'hostPath' volume mounts in MiCADO ADT
• Use the restart property in docker compose to manage the container restarts. The values can be always, on-failure or none.
• Use the long port syntax in docker-compose for services that needs to be exposed externally using a domain name or public IP. A sample of long port syntax is given below.

    ports:
     - target: 8080
       published:8080
       protocol: tcp
       mode: host

Docker Compose Variables

The variables in docker compose file needs to be in these form:

- TEST_MESSAGE={ get_input:TEST_MESSAGE }
TEST_MESSAGE: '{ get_input:TEST_MESSAGE }'
command: 'python3 start.py {get_input:DB_MODEL_}'

Roadmap

• Support appending translated nodes to an existing ADT
