 Use your favorite package manager on your own computer. Pip is preferred because the upstream packages it for themselves and it is in pure python. The general CS infrastructure will become a managed client for you to use in the near future (e.g., linux.cs.uchicago.edu). However, our experience has been that the software installs cleanly and is free from dependency problems.

 The command executed asynchronously, check the status:

 Here's an example for creating 10 of them, as promised (only the change at the end of the command)
-<code>openstack server create --image bionic-server-cloudimg-amd64.raw --boot-from-volume=32 --flavor m1.small --config-drive=true --user-data=/home/chudler/openstack/cluster_test/cloud-init.yml --network mynet moar --min 10 --max 10</code>

 Here's a nasty thing I use to determine what the security group is for a server (it can be determined also by looking at security groups directly) [ITS BRITTLE, BEWARE]
-<code>SEC_GROUP=$(openstack port list --server `openstack server show --format value --column id myserver` --long --column "Security Groups" --format json | jq '.[]."Security Groups"[]')</code>
+<code>
+SEC_GROUP=$(openstack port list \
+  --server `openstack server show --format value --column id myserver` \
+  --long \
+  --column "Security Groups" \
+  --format json \
+  | jq '.[]."Security Groups"[]' \
+  | sed 's/"//g')
+</code>
 If I learned the security group successfully, I can let in SSH. By default, **no communication is possible**.
