Questions tagged [kompose]

Kompose is a tool to convert Docker Compose YAML files to Kubernetes artifacts. Use this tag for questions about using the Kompose tool, including specific features of Docker Compose syntax and about adjusting or deploying the resulting Kubernetes YAML files.

Kompose is a tool to convert Docker Compose YAML files to Kubernetes artifacts. It is eases migration from a single-host Docker Compose setup to a full Kubernetes cluster.

Kompose does not support every Docker Compose feature; see the Kompose Conversion Matrix for an official summary. Some Docker features like host bind mounts or populating named volumes do not translate well into Kubernetes, and a Kompose-based conversion may need to make additional manual updates to the generated YAML.

Use this tag for questions about using the Kompose tool, including modifying the resulting YAML or porting specific Docker features. It frequently will make sense to also label these questions with or , since this tool intersects with both topics.
