Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

Development Phase:
Step 1: Create Certificate .pem from Certificate .p12
Command: openssl pkcs12 -clcerts -nokeys -out apns-dev-cert.pem -in apns-dev-cert.p12
Step 2: Create Key .pem from Key .p12
Command : openssl pkcs12 -nocerts -out apns-dev-key.pem -in apns-dev-key.p12
Step 3: Optional (If you want to remove pass phrase asked in second step)
Command : openssl rsa -in apns-dev-key.pem -out apns-dev-key-noenc.pem
