 3. Use the NS file to create a containerized experiment using the existing containers scripts (on users): {{{/share/containers/containerize.py [group] [experiment] [ns file]}}}. Note that the experiment must currently be created in the {{{Deter}}} group as that's where the custom images are. This will change. 
 
+4. Modify the NS file generated by {{{containerize.py}}} to have a new image for the pnode machines. Navigate to the new experiment page and click {{{Modify Experiment}}}. Change the OS type of the pnodes to {{{PNODE_BASE}}} and the hardware type to {{{MicroCloud}}}. I.e. for each pnode in the NS file, make the lines have the form:
+{{{
+    tb-set-node-os ${pnode(0000)} PNODE-CONT
+    tb-set-hardware ${pnode(0000)} MicroCloud
+}}}
+Remove all existing {{{tb-set-node-startcmd}}} lines as these start the old containers system.

 The final NS file will look something like this.

+5. Populate the configuration database that runs on {{{chef.isi.deterlab.net}}} by running the database population scripts. (This will automated in the future.) This should be run from a physical node in the experiment. I use {{{pnode-0000}}} in the example below.

-5. Swap in the experiment and wait a long time. There is no great way to tell when the containers are up, unfortunately. Tail the start-cmd output on the {{{config}}} node and look for the "complete" message.

 Fun things to do after the containers are running.
