Docker

Create a docker.env file containing your access keys:

TWITTER_CONSUMER_KEY=...
TWITTER_CONSUMER_SECRET=...
TWITTER_ACCESS_TOKEN=...
TWITTER_ACCESS_TOKEN_SECRET=...
NASA_API_KEY=...

Then you can easily build and run your container:

Build and push your built container to dockerhub or your own private registry:

docker build -t <registry>/emojiart:latest .
docker push <registry>/emojiart:latest

Update the image path in the emojiart.yaml file to point to your built container.

image: <registry>/emojiart:latest
