GovStack Sandbox

This project provides scripts for creating and configuring GovStack sandbox environments.

We use Ansible for scripting and Digital Ocean for hosting. These Ansible scripts borrow from ssdnodes-ansible-provision

See the Functional demo sandbox tasks for more details on this project.

Initial setup

1. Ensure you have an Ansible Control Node, e.g. ansible.egovstack.net on Digital Ocean.
2. Check out a copy of this repo on the control node. We suggest creating unique forks/branches to track changes and regularly committing/pushing them to track configuration changes over time.
3. Copy vars_with_secret_example.yml to vars_with_secret.yml. It contains shared secrets used across scripts.

Create Digital Ocean droplets

1. Edit digital_ocean_token in vars_with_secret.yml to include your API Token and SSH keys for access. To create a Digital Ocean API token, see API -> Tokens/Keys -> Generate New Token. Be sure to create tokens with read/write privileges.
2. Edit ssh_key_fingerprint in vars_with_secret.yml to include the fingerprint of the Digital Ocean SSH key to be added to new droplets. You can add a new SSH key, or use the existing host@ansible SSH key in Digital Ocean. To get the fingerprint of an existing SSH key for an existing Digital Ocean SSH key, see your team's security settings, e.g. Account Settings -> Security -> SSH Keys.
3. Edit the hosts file to include your new droplets. Droplets of the same type should have the same prefix, e.g.:

...

#eregistration
[ereg]
er1.egovstack.net
er2.egovstack.net

...

NOTE: hostnames must include a number, e.g. er1

4. Edit digitalocean.yml to include the correct starting image and droplet type, e.g.:

    droplet_image:
      er: ubuntu-18-04-x64
    droplet_size:
      er: s-2vcpu-4gb

5. Use the digitalocean.yml Ansible script to create all droplets:

$ ansible-playbook -i ./hosts digitalocean.yml

6. Use the drop.yml Ansible script to destroy droplets.

$ ansible-playbook -i ./hosts drop.yml

Note that you may need to run this multiple times to remove all subdomains...

Set up SSL certificates and SSH access to droplets

1. Add known hosts to all droplets:

$ ANSIBLE_HOST_KEY_CHECKING=false ansible-playbook -i hosts store_known_hosts.yml

NOTE: if this script fails for any reason, you likely need to clean references to old hosts from the ~/.ssh./known_hosts file on the Ansible Control Node.

If you see an error like dig +short er3.egovstack.net you likely need to wait a minute for the DNS update from digitalocean.yml to propagate.

2. This playbook creates non-root user, updates packages, configures SSH access, and generates LetsEncrypt certificates for all droplets. On ansible.egovstack.net, hit <enter> for the forst SSH password: prompt. Use password from vars_with_secret.yml for the BECOME password[defaults to SSH password]: prompt. :

$ ansible-playbook -i hosts -k provision.yml --ask-become-pass

3. OPTIONAL: Reboot all droplets. On ansible.egovstack.net, use password from vars_with_secret.yml for the BECOME password: prompt:

$ ansible --ask-become-pass -i hosts -b -m reboot all

Set up Information Mediator

See Installing X-Road on DigitalOcean for more details on how to set up the XRoad as an Information Mediator.

Set up ERegistration

1. Set up eregistration:

$ ansible-playbook -i hosts -k ereg_coresystem.yml --ask-become-pass

2. Wait several minutes for everything to start up. You can ssh into the host to debug, e.g. from ansible.egovstack.net run host@ansible:~/wkd/ereg$ ssh root@er3.egovstack.net. It may be helpful to reboot the host a few times and run top or docker ps to see which processes are healthy.

3. Ensure keycloak has started up completely, then comment out KEYCLOAK_USER=$KEYCLOAK_ADMIN_USER and KEYCLOAK_PASSWORD=$KEYCLOAK_ADMIN_USER_PASSWORD in the docker compose, e.g. # vim /opt/eregistrations/compose/eregistrations/docker-compose.yml followed by docker-compose up -d keycloak
