Modify the script with with your Docker Hub repo name, image name, Droplet domain/address, and Dokku app name.
Ensure your Droplet is configured and accessible via SSH, and you are logged in to Docker Hub.
Domain, proxying and SSL certificates should already be set up, and the application must be created.
The create-app.sh script can be run to set up your app. Don't forget to run chmod +x create-app.sh The script requires that SSL certs have already been uploaded, as below. If using the letsencrypt plugin, configure your app manually, or alter the script as needed.
This application deploys to the root domain.
dokku apps:create <app-name>
dokku domains:clear-global
dokku domains:set <app-name> <domain>
dokku proxy:ports-set <app-name> http:80:<port-exposed-by-docker-container>
If adding an existing cert/key pair, they must be named server.crt and server.key and put in a .tar file named cert-key.tar then uploaded to your Droplet.
tar cvf cert-key.tar server.crt server.key
scp cert-key.tar root@<domain.tld>:/root
In your Droplet:
dokku certs:add <app-name> < cert-key.tar
Alternatively, you can use the dokku-letsencrypt plugin.
*letsencrypt will rate limit to 5 API calls per 7 day period.
