Moving past Docker on Mac, IBM Containers on Bluemix

Having tinkered with WebSphere Liberty Profile on Docker over the past few days, as per recent posts to this blog, I wanted to go one stage further, and recreate a similar WLP / application on IBM Containers, which runs on IBM Bluemix.



I'm definitely on the on-ramp for Bluemix, and the learning curve still looks rather steep …

For reference: -

Troubleshooting for accessing Bluemix

Logging in to the IBM Containers CLI plug-in (cf ic)


IBM® Bluemix® uses the Cloud Foundry command line interface, cf, to modify applications, service instances, and service bindings. You can also use Bluemix command line tool that provides extended experience to manage your Bluemix environment besides Cloud Foundry applications.

Command Line Interface reference

Bluemix CLI

Deploying your app with the command line interface

But here goes….

Download and Install Prerequisites

Bluemix_CLI_0.4.1.pkg
cf-cli-installer_6.21.1_osx.pkg
DockerToolbox-1.12.0.pkg

Sources

Deploying your app with the command line interface

Docker Toolbox

Fix up .cf subdirectory to avoid panic

panic: Config error: open /Users/davidhay/.cf/config.json: permission denied

sudo chmod -R 777 /Users/davidhay/.cf/

Connect to Bluemix

bluemix api https://api.ng.bluemix.net

Log in to Bluemix - may NOT need this, as we also login using Cloud Foundry (CF) CLI

bluemix login -u david_hay@uk.ibm.com -o david_hay@uk.ibm.com -s david_hay

-OR- use the SSO variant: -

bluemix login -sso -u david_hay@uk.ibm.com -o david_hay@uk.ibm.com -s david_hay

having got a passcode from here: -

https://login.ng.bluemix.net/UAALoginServerWAR/passcode

Install Mac Containers plugin for Cloud Foundry

cf install-plugin https://static-ice.ng.bluemix.net/ibm-containers-mac

Validate plugin

cf plugins

Set IBM Containers Namespace

cf ic namespace set david_hay

Initialise IBM Containers CLI

cf ic init

Check available images

cf ic images

Start WebSphere Liberty Profile container

foobar=`cf ic run -d -t -p 80:9080 -p 443:9443 ibmliberty:latest`

See what's running

cf ic ps -a

CONTAINER ID        IMAGE                                          COMMAND             CREATED             STATUS                  PORTS               NAMES

Deploy an application to WLP

cf ic cp ~/Downloads/ferret.war $foobar:/opt/ibm/wlp/usr/servers/defaultServer/dropins

Run a command against the container

cf ic exec -it $foobar /bin/bash

Monitor the container logs

cf ic logs $foobar -f 

Functionally test the Ferret app

http://localhost/ferret/

https://localhost/ferret

Stop the container

cf ic stop $foobar

Remove the container

cf ic rm $foobar

Log out from Cloud Foundry

cf logout

Log out from Bluemix

bluemix logout

PS Remember the tagline for my blog …. YMMV
