Quick Start

Deploying apps is easy once you've installed Ketch. First, create a pool. Then create app(s) adding them to the pool and finally
deploy the app(s). The following example illustrates these steps.

# Add a pool with ingress Traefik (default), replace ingress IP address by your ingress IP address
ketch pool add mypool  --ingress-service-endpoint 35.247.8.23 --ingress-type traefik

# Create app
ketch app create bulletinboard --pool mypool       

# Deploy app
ketch app deploy bulletinboard -i docker.io/shipasoftware/bulletinboard:1.0 

# Check app status
ketch app list 

NAME             POOL        STATE        ADDRESSES                                      PLATFORM    DESCRIPTION
bulletinboard    mypool      1 running    http://bulletinboard.35.247.8.23.shipa.cloud

After you deploy your application, you can access it at the address associated with it using the ketch app list, in
this example bulletinboard.35.247.8.23.shipa.cloud.
