NOTE: This repo is provided without any support, but should be able to get you closer to getting Calamari running on RHEL6. Feel free to submit a PR if you would like to make additions, and they'll be reviewed.

Calamari builder for Redhat (RHEL 6)

What it does

Creates a Calamari build for RedHat 6. As the Octopus-supplied Calamari is built against RHEL7, it uses a higher version of glibc than is available on RHEL6. This tool will pull down the latest tagged Calamari release and compile it to be compatible with RHEL/CentOS 6 systems.

Using this tool

This script will need to be run on a linux machine that has:

• git
• Docker and run from a user with access to manipulate docker on the machine. Worst case, you can run the script via sudo (with all the usual caveats, read the scripts and know what they do etc.)

1. Ensure that the docker service is running on the machine, and the current user has access to the docker engine.
2. Verify the version of Calamari your Octopus server uses, performing a healthcheck on the target will reveal this data.
3. git clone this repo onto the machine.
4. Set the GIT_VERSION environmental variable to the calamari version you need.
5. Run ./build.sh
6. When the script finishes, you should find the file in the artifacts-history folder, named calamari-rhel.6-x64-<VERSION>.tar.gz

NOTE: If the filename does not have a valid version, and is just named calamari-rhel.6-x64-.tar.gz, it's very likely something has gone wrong with the script (Docker service not running, user doesn't have access etc.). Please be sure to look at the logs and rectify what's wrong.

Using the compiled Calamari package.

1. Create an SSH target in the Octopus server for your RHEL 6 server.
2. Do a sample deployment, which will fail due to the shipped Calamari version not being compatible. This will build all of the directory structure.
3. Copy/scp the output file of the script onto the server.
4. Navigate to ~/.octopus/OctopusServer/Tools/Calamari.linux-x64/<VERSION>/ for the SSH user that Octopus uses, and delete the Calamari install there.
5. Extract the custom version to the directory in the previous step and touch Success.txt to generate this file.
6. Enjoy deploying to RHEL 6!

What could go wrong?

• Calamari core dumps not being able to file ICU libraries.

Assuming you followed the directions Microsoft's instructions, you will likely need to add the export LD_LIBRARY_PATH=/usr/local/lib to your .bashrc file.

• I updated Octopus, and now my deployments are failing!

You will likely need to repeat the steps for the new version of Calamari that ships with your upgraded version.
