docker-uemcli

A Docker container to simplify running EMC's uemcli utility for the management of VNX-based storage systems.

Requirements

A few things are required to use this utility on your machine:

• a fairly recent Docker installation
• a compatible EMC storage system (e.g. the EMC Unity® family)
• the binary RPM package of uemcli from EMC (you will actually have to login). Note that this will not work on VNXe systems; your have to download a different binary.

Beware that uemcli does not support older EMC storage systems. You might want to take a look at my repository for Navisphere-based systems.

Installation and Usage

Because I can't redistribute the original RPM, you have to build your own local Docker image, like so:

1. Clone this repository.
2. Drop the downloaded RPM in the same folder as the Dockerfile.
3. Open a shell and run

docker image build . -t local/uemcli:4.1.1.1.3836-1 -t local/uemcli:latest

After that, you can execute

docker run -ti --rm --volume ~/.emc:/root/.emc local/uemcli

on your favourite shell.

During the first run, uemcli will (provided that you successfully login to your storage system and pass the --save-user switch to it) store your encrypted credentials on the mounted container volume. Subsequent runs will pick them up and use them to seamlessly authenticate you.

If you happen to be lazy, feel free to take a look at the uemcli.alias (using the alias BUILTIN of sh(1) under *NIX) or uemcli.alias.cmd (using the DOSKEY utility under Windows) file; make sure that it gets processed by your shell, and you can run the command by it's name directly.

Note that this is not a tutorial on how to use uemcli; EMC did a great job in writing a comprehensive user manual; for quick help, try to run

$ uemcli -help

to get a few details on the most common parameters and switches, but since the command is quite powerful, I recommend you to RTFM.
