Compose is a sub-command for defining and running multi-container applications. With this, you use a Compose file to configure your application’s services. Then, using a single command, you create and start all the services from your configuration in Hyper cloud.
Compose is great and easy to test and deploy your production, as well as CI workflows. You can learn more about each case in Common Use Cases.
Using Compose is basically a three-step process.
- Define your app’s Docker Images and push them to Docker hub or private registry, so it can be reproduced anywhere.
- Define the services that make up your app in docker-compose.yml so they can be run together in an isolated environment.
- Lastly, run
hyper compose upand Compose will start and run your entire app.
We need a floating ip first:
$ hyper fip allocate 1 Please note that Floating IP (FIP) is billed monthly ($1). The billing begins when a new IP is allocated, ends when it is released. Partial month is treated as a entire month. Do you want to continue? [y/n]: y 22.214.171.124
A docker-compose.yml looks like this (remember to change the FIP):
version: '2' services: web: image: wordpress:latest fip: 126.96.36.199 links: - db:mysql depends_on: - db ports: - "8080:80" db: image: mysql:latest ports: - "3306" environment: - MYSQL_ROOT_PASSWORD=my-secret-pw
Now you can run
hyper compose up and visit your wordpress blog on http://188.8.131.52
For more information about the Compose file, see the Compose file reference
Compared with docker compose specification, hyper compose support two more fields:
size- container size for the service, we support ten different sizes, you can find more details at here.
fip- floating IP for service
Compose has commands for managing the whole lifecycle of your application:
- Start, stop services
- View the status of running services
- Stream the log output of running services
- Run a one-off command on a service
