uptime-kuma-nginx-acme

Like in the name, this is a combination of uptime-kuma, nginx and acme.sh, with SSL-auto-renewing function, as a docker compose project.

Setup

Assume your domain is uptime.mysite.com.

Create nginx site config file: cp config/nginx/conf.d/web.conf.example config/nginx/conf.d/web.conf
Replace all uptime.example.com with uptime.mysite.com in config/nginx/conf.d/web.conf file
Initial start: docker-compose up -d
Getting certs: docker-compose exec acme --issue -d uptime.mysite.com --webroot /fake-www --server letsencrypt
Comment out fake ssl config (and uncomment the real ones) in config/nginx/conf.d/web.conf
Stop it: docker-compose down

Adding SMTP relay support

To send notifications via SMTP you can use a local Postfix working as relay. You'll also need a service like Sendgrid, AWS SES or similar to do the final delivery.

To use the local SMTP you'll have to:

Create the local docker compose override: cp docker-compose.override.yml.example docker-compose.override.yml
Configure it with your relay host credentials, see: https://hub.docker.com/r/alterrebe/postfix-relay/
Setup the uptime-kuma Email (SMTP) notification using smtp as Hostname, Port 25, no security and no username/password

Start

docker-compose up -d

Stop

docker-compose down

Integrate with docker swarm

Edit docker-compose.yml, change network section to:

networks:
  uptime-net:
    external: true
    driver: overlay
