Deis v1 Cheatsheet

A comprehensive cheat sheet for Deis v1, covering essential commands for deploying, configuring, and managing applications.

Application Deployment

Basic Deployment

deis create <app-name> - Create a new application.
If app name is not specified, it is generated automatically.

Example:
deis create my-web-app

git push deis master - Deploy the application using Git.
This command assumes that the deis remote is properly configured.

Example:
Add remote:
git remote add deis deis@<deis-controller>:<app-name>
Then deploy:
git push deis master

deis open - Open the application in a web browser.

deis apps:info - Retrieve application information.

deis apps:list - List all applications.

deis apps:destroy - Delete the application.

Dockerfile Deployment

deis pull <image-name> - Deploy an application from a Docker image.

Example:
deis pull redis:latest

If a Dockerfile is present in the root directory, Deis automatically builds the application.

The default process type when using dockerfile is cmd.

Check the logs to see the result:
deis logs
