+# Tools to create lab environments
+
+This directory contains tools to create lab environments for Docker and Kubernetes courses and workshops.
+
+It also contains Terraform configurations that can be used stand-alone to create simple Kubernetes clusters.
+
+Assuming that you have installed all the necessary dependencies, and placed cloud provider access tokens in the right locations, you could do, for instance:
+
+```bash
+# For a Docker course with 50 students,
+# create 50 VMs on Digital Ocean.
+./labctl create --students 50 --settings settings/docker.env --provider digitalocean
+
+# For a Kubernetes training with 20 students,
+# create 20 clusters of 4 VMs each using kubeadm,
+# on a private Openstack cluster.
+./labctl create --students 20 --settings settings/kubernetes.env --provider openstack/enix
+
+# For a Kubernetes workshop with 80 students,
+# create 80 clusters with 2 VMs each,
+# using Scaleway Kapsule (managed Kubernetes).
+./labctl create --students 20 --settings settings/mk8s.env --provider scaleway --mode mk8s
+```
+
+Interested? Read on!
+
+## Software requirements
+
+For Docker labs and Kubernetes labs based on kubeadm:
+
+- [Parallel SSH](https://github.com/lilydjwg/pssh)
+  (should be installable with `pip install git+https://github.com/lilydjwg/pssh`;
+  on a Mac, try `brew install pssh`)
+
+For all labs:
+
+- Terraform
+
+If you want to generate printable cards:
+
+- [pyyaml](https://pypi.python.org/pypi/PyYAML)
+- [jinja2](https://pypi.python.org/pypi/Jinja2)
+
+These require Python 3. If you are on a Mac, see below for specific instructions on setting up
+Python 3 to be the default Python on a Mac. In particular, if you installed `mosh`, Homebrew
+may have changed your default Python to Python 2.
+
+You will also need an account with the cloud provider(s) that you want to use to deploy the lab environments.
+
+## Cloud provider account(s) and credentials
+
+These scripts create VMs or Kubernetes cluster on cloud providers, so you will need cloud provider account(s) and credentials.
+
+Generally, we try to use the credentials stored in the configuration file used by the cloud providers CLI tools.
+
+This means, for instance, that for Linode, if you install `linode-cli` and configure it properly, it will place your credentials in `~/.config/linode-cli`, and our Terraform configurations will try to read that file and use the credentials in it.
+
+You don't **have to** install the CLI tools of the cloud provider(s) that you want to use; but we recommend that you do.
+
+If you want to provide your cloud credentials through other means, you will have to adjust the Terraform configuration files in `terraform/provider-config` accordingly.
+
+## General Workflow
+
+- fork/clone repo
+- make sure your cloud credentials have been configured properly
+- run `./labctl create ...` to create lab environments
+- run `./labctl destroy ...` when you don't need the environments anymore
+
+## Customizing things
+
+You can edit the `settings/*.env` files, for instance to change the size of the clusters, the login or password used for the students...
+
+Note that these files are sourced before executing any operation on a specific set of lab environments, which means that you can set Terraform variables by adding lines like the following one in the `*.env` files:
+
+```bash
+export TF_VAR_node_size=GP1.L
+export TF_VAR_location=eu-north
+```
+
+## `./labctl` Usage
+
+If you run `./labctl` without arguments, it will show a list of available commands.
+
+### Summary of What `./labctl` Does For You
+
+The script will create a Terraform configuration using a provider-specific template.
+
+There are two modes: `pssh` and `mk8s`.
+
+In `pssh` mode, students connect directly to the virtual machines using SSH.
+
+The Terraform configuration creates a bunch of virtual machines, then the provisioning and configuration are done with `pssh`. There are a number of "steps" that are executed on the VMs, to install Docker, install a number of convenient tools, install and set up Kubernetes (if needed)... The list of "steps" to be executed is configured in the `settings/*.env` file.
+
+In `mk8s` mode, students don't connect directly to the virtual machines. Instead, they connect to an SSH server running in a Pod (using the `jpetazzo/shpod` image), itself running on a Kubernetes cluster. The Kubernetes cluster is a managed cluster created by the Terraform configuration.

+
+The directory structure can feel a bit overwhelming at first, but it's built with specific goals in mind.
+
+**Consistent input/output between providers.** The per-provider configurations in `one-kubernetes` all take the same input variables, and provide the same output variables. Same thing for the per-provider configurations in `virtual-machines`.
+
+**Don't repeat yourself.** As much as possible, common variables, definitions, and logic has been factored in the `common.tf` file that you can see in `one-kubernetes` and `virtual-machines`. That file is then symlinked in each provider-specific directory, to make sure that all providers use the same version of the `common.tf` file.
+
+**Don't repeat yourself (again).** The things that are specific to each provider have been placed in the `providers` directory, and are shared between the `one-kubernetes` and the `virtual-machines` configurations. Specifically, for each provider, there is `config.tf` (which contains provider configuration, e.g. how to obtain the credentials for that provider) and `variables.tf` (which contains default values like which location and which VM size to use).
+
+**Terraform configurations should work in `labctl` or standalone, without extra work.** The Terraform configurations (identified by 🌍 in the directory tree above) can be used directly. Just go to one of these directories, `terraform init`, `terraform apply`, and you're good to go. But they can also be used from `labctl`. `labctl` shouldn't barf out if you did a `terraform apply` in one of these directories (because it will only copy the `*.tf` files, and leave alone the other files, like the Terraform state).
+
+The latter means that it should be easy to tweak these configurations, or create a new one, without having to use `labctl` to test it. It also means that if you want to use these configurations but don't care about `labctl`, you absolutely can!
+
+## Miscellaneous info
+
+### Making sure Python3 is the default (Mac only)
+
+Check the `/usr/local/bin/python` symlink. It should be pointing to
+`/usr/local/Cellar/python/3`-something. If it isn't, follow these
+instructions.
+
+1) Verify that Python 3 is installed.
+
+```
+ls -la /usr/local/Cellar/Python
+```
+
+You should see one or more versions of Python 3. If you don't,
+install it with `brew install python`.
+
+2) Verify that `python` points to Python3.
+ 
+```
+ls -la /usr/local/bin/python
+```
+
+If this points to `/usr/local/Cellar/python@2`, then we'll need to change it.
+
+```
+rm /usr/local/bin/python
+ln -s /usr/local/Cellar/Python/xxxx /usr/local/bin/python
+# where xxxx is the most recent Python 3 version you saw above
+```
+
+### AWS specific notes
+
+Initial assumptions are you're using a root account. If you'd like to use a IAM user, it will need the right permissions. For `pssh` mode, that includes at least `AmazonEC2FullAccess` and `IAMReadOnlyAccess`.
+
+In `pssh` mode, the Terraform configuration currently uses the default VPC and Security Group. If you want to use another one, you'll have to make changes to `terraform/virtual-machines/aws`.
+
+The default VPC Security Group does not open any ports from Internet by default. So you'll need to add Inbound rules for `SSH | TCP | 22 | 0.0.0.0/0` and `Custom TCP Rule | TCP | 8000 - 8002 | 0.0.0.0/0`.
