Build and push the application to a Docker registry

Before you can run the application on the cluster, you first need to push the Docker image to the IBM Cloud private container registry.

1. Set MYPROJECT environment variable. Replace with the name of the application you created in the previous steps.
   Windows

   Bash

   set MYPROJECT=<APP_NAME>

   export MYPROJECT=<APP_NAME>

2. Set MYNAMESPACE and MYREGISTRY and env vars. Copy and paste these commands.
   Windows

   Bash

   set MYNAMESPACE=think-iks
   set MYREGISTRY=registry.ng.bluemix.net

   export MYNAMESPACE=think-iks 
   export MYREGISTRY=registry.ng.bluemix.net

3. Build and tag (-t) the docker image
   Windows

   Bash

   docker build . -t %MYREGISTRY%/%MYNAMESPACE%/%MYPROJECT%:v1.0.0

   docker build . -t $MYREGISTRY/$MYNAMESPACE/$MYPROJECT:v1.0.0

4. Ensure you are logged into the IBM container registry

   ibmcloud cr login
   

5. Push the docker image to your container registry on IBM Cloud
   Windows

   Bash

   docker push %MYREGISTRY%/%MYNAMESPACE%/%MYPROJECT%:v1.0.0

   docker push $MYREGISTRY/$MYNAMESPACE/$MYPROJECT:v1.0.0
