Ubuntu + Nginx + SSL

---

SSL Setup with Lets Encrypt

• This example is for Multi Domain SSL Setup.
• If you are planning for single domain, you can ignore 2nd docker/domain.

Step: 1

Dependancy for SSL

$ apt update

$ apt install certbot python3-certbot-nginx

Create Network

$ docker network create web

Step: 2

Build docker image

docker build -t my-docker-app .

docker build -t my-docker-app2 .

Run Docker images with domain name and use the same in nginx.conf

docker run -d --name domain1.com --network web my-docker-app

docker run -d --name domain2.com --network web my-docker-app2

Create LetsEncrypt SSL Certificate

$ certbot -d domain1.com -d domain2.com

Config the Nginx

• Update the env.sh with your data $ bash env.sh

Command to Run Nginx

$ docker run --name nginx --network web -p 80:80 -p 443:443 -v ./nginx.conf:/etc/nginx/nginx.conf -v /etc/letsencrypt/:/etc/letsencrypt/ nginx

Note:*

• 1. Update the domain name as per the image name
• 2. Update the (SSL) certificate and key file location
• 3. Mount nginx.conf and letsencrypt as virtual dir
• 4. Test Image: shankarthiyagu/hello-world
