Tinkering with IBM Containers on IBM Bluemix - Like Docker really ...

As per previous posts, I have been tinkering with IBM Containers (IC) on IBM Bluemix, and am starting to bring things together in my mind, in terms of positioning IC vs. Kubernetes vs. Docker.

One of the many things that I like is the amount of help and choices that one has.

Having initialised the Bluemix ( bc ) Cloud Foundry ( cf ) IBM Containers ( ic ) environment: -

bx cf ic init

Invoking 'cf ic init'...

Deleting old configuration file...
OK
Generating client certificates for IBM Containers...
Client certificates are being stored in /Users/foobar/.ice/certs/...

Client certificates are being stored in /Users/foobar/.ice/certs/containers-api.eu-gb.bluemix.net/21377cbf-6e5f-4a9a-175a-4fdfeb3c3e12...

OK
Client certificates were retrieved.

Checking local Docker configuration...
OK

Authenticating with registry at host name registry.eu-gb.bluemix.net
OK
You are authenticated with IBM Bluemix Container Registry.
Your private Bluemix repository is URL: registry.eu-gb.bluemix.net/foobar
No ic-cfg.ini found on the system. Creating...

You can choose from two ways to use the Docker CLI with IBM Containers:


Option 1: This option allows you to use 'cf ic' for managing containers on IBM Containers while still using the Docker CLI directly to manage your local Docker host.
Use this Cloud Foundry IBM Containers plug-in without affecting the local Docker environment:


Example Usage:
cf ic ps
cf ic images

Option 2: Use the Docker CLI directly. In this shell, override the local Docker environment to connect to IBM Containers by setting these variables. Copy and paste the following commands:
Note: Only Docker commands followed by (Docker) are supported with this option. 
  export DOCKER_HOST=tcp://containers-api.eu-gb.bluemix.net:8443
  export DOCKER_CERT_PATH=/Users/foobar/.ice/certs/containers-api.eu-gb.bluemix.net/21377cbf-6e5f-4a9a-175a-4fdfeb3c3e12
  export DOCKER_TLS_VERIFY=1

Example Usage:
docker ps
docker images



it's great to see that I can use either cf ic commands: -

cf ic ps
