Installing and using

No root privileges are required to install or use this code.

Verify the ordering is not buggy:


In [1]: from conda.resolve import normalized_version as nv

In [2]: a = nv('master_gac1855abae.0125')

In [3]: b = nv('master.20150626170402.post157')

In [4]: c = nv('master.20150928224422.post8')

Setting up Docker with user namespaces on CentOS 7.4

The procedure below has been tested on a Digital Ocean VM with CentOS 7.4

# Install docker from RHEL’s standard repos
yum install -y docker

#
# We’ll activate the ‘user namespaces’ feature that defends against

Utilities you'll care about

All these are already installed on epyc.

kafkacat (conda install -c conda-forge kafkacat)
kt (grab it from https://github.com/fgeller/kt/releases)
kafka-* (come with kafka, if you yum install if from Confluent's repo, or via Docker if you're so inclined). Warning -- JVM based and dreadfully slow.
jq (conda install -c conda-forge jq or use your favorite package manager)

Making your own (editable) clone of the SSSC conda environment and Jupyter kernel

This gist describes how to clone the SSSC conda environment (and jupyter kernel) on epyc into your own directory where you can install your own packages into.

This will continue using the LSST stack from the SSSC directory, but you will be able to override (i.e., setup, in the EUPS sense) individual packages by editing your copy of env-setup.sh (see below).
