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

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.

Inline swarm configs with envsubst

export NGINX_FOLDER=html

services:
  nginx:
    configs:
      /etc/nginx/conf.d/default.conf:
        content: |
          server {
            location / {
              root ${NGINX_FOLDER};
            }
          }
