What?

Deploy application to docker swarm in a controlled manner.

Why?

• Rolling update of swarm config, thanks to checksum naming
• Explicit syntax, no more optionals, no more short syntax
• Built-in jinja2 style templating via nunjucks
• Inline swarm configs with envsubst

Usage

• swarm-app validate will exit on basic configuration file mistakes.
• swarm-app diff gives a proper diff overview of what you are about to deploy.
• swarm-app deploy deploys the application.
• swarm-app wait waits for deployment to reconcile, and outputs status.
