nginx-certbot

Docker Swarm deployment for Nginx edge proxies, with Certbot renewals and log shipping.

Usage

Tested on Ubuntu 22.04. This project is used to build and deploy a Docker Swarm stack intended to be used in conjunction with the department's Nginx and LetsEncrypt configuration.

A sample script (build-host.sh) is included which assumes that you have a /var/nginx-etc directory set up with your config directories, ready for deployment.

Upgrading

• Edit Dockerfile.nginx (typically the lines FROM nginx:1.* and the RUN apt-get -y install nginx-module-sigsci-nxo=1.*).
• Test build the image: docker image build --file Dockerfile.nginx --tag ghcr.io/dbca-wa/nginx-sigsci .
• Edit Dockerfile.certbot (typically the lines FROM certbot/dns-cloudflare:v2.* and RUN pip install certbot-dns-azure==2.*).
• Test build the image: docker image build --file Dockerfile.certbot --tag ghcr.io/dbca-wa/certbot-dns-cloudflare-azure .
• Edit the docker-compose.yml file to ensure that the "latest" just-built versions of the nginx and certbot images will be used (do not commit this change).
• Deploy those new images to the local host, check normal functioning: docker stack deploy nginx -c docker-compose.yaml
• Assuming all is well, tag the two built images, update docker-compose.yml to use those tagged image versions, commit and push everything (commits and images) to GitHub.
