Example: build an image

compose builds the image on your docker engine on every deploy, so the project's own code goes live with each push.

Files #

Dockerfile

1FROM busybox:1.37
2COPY site/ /www/
3EXPOSE 8080
4CMD ["httpd", "-f", "-p", "8080", "-h", "/www"]

site/index.html

1<h1>hello from picd</h1>

compose.yaml

 1services:
 2  web:
 3    build: .
 4    labels:
 5      - traefik.enable=true
 6      - traefik.http.routers.site.rule=Host(`site-alice.user.cd.pico.sh`)
 7      - traefik.http.services.site.loadbalancer.server.port=8080
 8    networks: [picd-ingress]
 9networks:
10  picd-ingress:

The port label tells Traefik which port the container serves.

Deploy #

1git init -b main && git add . && git commit -m init
2git push ssh://cd.pico.sh/site.git main
3curl https://site-alice.user.cd.pico.sh

Edit site/index.html, commit, and push again to rebuild and redeploy.
