## Running the workshop
WARNING: those instructions are incomplete. Consider
them as notes quickly drafted on a napkin rather than
proper documentation!
General timeline of planning a workshop
- Run through slides, doing the hands-on to be sure you understand the different `dockercoins` repo's and the steps we go through to get to a full Swarm Mode cluster of many containers.
- This workshop expects 5 servers per student. You can get away with as little as 2 servers per student, but you'll need to change the slide deck to accomidate.
- AWS is our most tested process for generating student machines. In `prepare-vms` you'll find scripts to create EC2 instances, install docker, pre-pull images, and even print "cards" to place at each students seat with IP's and username/password.
- Be sure to test creating *all* your needed servers a week before workshop. You'll likely hit AWS limits in the region closest to your class, and it sometimes takes days to get AWS to raise those limits with a support ticket.
- Typically we create the servers the day before or morning of workshop, and leave them up the rest of day after workshop. If creating hundreds of servers, you'll likely want to run all these `trainer` commands from a dedicated instance you have in same region as instances you want to create.
- Remember you'll need to print the "cards" for students, so you'll need to create instances while you have a way to print them.
### Creating the VMs
I use the `trainctl` script from the `docker-fundamentals`
repository. Sorry if you don't have that!
`prepare-vms/trainer` is the script that gets you most of what you need for setting up instances. See `prepare-vms/README.md` for more info.
After starting the VMs, use the `trainctl ips` command
to dump the list of IP addresses into a file named `ips.txt`.
