so I am trying to deploy the following image osticket/osticket - Docker Image | Docker Hub

In the quick start guide, they have this command line docker run commands for both mysql and the application osticket.

Quick Start Ensure you have a MySQL container running that osTicket can use to store its data.

docker run --name osticket_mysql -d -e MYSQL_ROOT_PASSWORD=secret
-e MYSQL_USER=osticket -e MYSQL_PASSWORD=secret -e MYSQL_DATABASE=osticket mariadb Now run this image and link the MySQL container.

docker run --name osticket -d --link osticket_mysql:mysql -p 8080:80 osticket/osticket When I execute these two commands exactly as shown above, the website works via http://localhost:8080/scp/

Now, I tried to put the same into a docker-compose.yaml file:

version: ‘3.8’
services:
osticket:
container_name: osticket-web
image: osticket/osticket
environment:
MYSQL_HOST: db
MYSQL_PASSWORD: secret
depends_on:

• db
  ports:
• 8080:80
  db:
  container_name: osticket-db
  image: mysql
  restart: always
  environment:
  MYSQL_ROOT_PASSWORD: secret
  MYSQL_DATABASE: osticket
  MYSQL_USER: osticket
  MYSQL_PASSWORD: secret
  when I look at the status, the osticket-web exits

NAME COMMAND SERVICE STATUS PORTS osticket-db “docker-entrypoint.s…” db running 3306/tcp, 33060/tcp osticket-web “entrypoint” osticket exited (1)

Looking at the logs it says:

Install/Update osTicket

OSTicket cron job is set to run every 5 minutes

Waiting for database TCP connection to become available...
Connecting to database mysql://osticket@db/osticket

Thank you.
