On the teleport server:

1. Create a short lived token to “invite” the MaaS application
   • tctl tokens add --type=app,node --app-name=<dc>-maas --app-uri=http://localhost:5240
   • Take note of the token and ca_pin values

On the maas server:

1. Install the Teleport agent:
   • sudo curl https://goteleport.com/static/install.sh | bash -s <teleport version>
2. create the Teleport application config:
   • sudo teleport configure --output=file --proxy=<domain name>:443 --token=/var/lib/teleport/token --roles=app,node --app-name=<dc>-maas --app-uri=http://localhost:5240
   • 
3. Save the token generated on the Teleport server:
   • sudo vi /var/lib/teleport/token
   • 
4. Save the ca_pin generated on the Teleport server:
   • sudo vi /var/lib/teleport/ca_pin
   • 
5. Edit the /etc/teleport.yaml to update the ca_pin resource:
   • sudo vi /etc/teleport.yaml
   • Update the ca_pin resource with the file path to the token /var/lib/teleport/ca_pin
   • Add labels: section under ssh_service:

     labels:
         dc: "<dc>"
         login: "<admin user login>"
     

   • Remove commands: section under ssh_service:

     commands:
       - name: hostname
         command: [hostname]
         period: 1m0s
     

   • Add labels: under app_service: -> apps: -> <dc>-maas service

     - name: <dc>-maas
         uri: http://localhost:5240
         public_addr: ""
         insecure_skip_verify: false
         labels:
           dc: "<dc>"
           type: "maas"
     

   • Sample /etc/teleport.yaml file

      1version: v3
      2teleport:
      3  nodename: maas
      4  data_dir: /var/lib/teleport
      5  join_params:
      6    token_name: /var/lib/teleport/token
      7    method: token
      8  proxy_server: teleport.<domain>:443
      9  log:
     10    output: stderr
     11    severity: INFO
     12    format:
     13      output: text
     14  ca_pin: /var/lib/teleport/ca_pin
     15  diag_addr: ""
     16auth_service:
     17  enabled: "no"
     18ssh_service:
     19  enabled: "yes"
     20  labels:
     21    dc: "<dc>"
     22    login: "maas"
     23proxy_service:
     24  enabled: "no"
     25  https_keypairs: []
     26  https_keypairs_reload_interval: 0s
     27  acme: {}
     28app_service:
     29  enabled: "yes"
     30  debug_app: false
     31  apps:
     32  - name: bo1-maas
     33    uri: http://localhost:5240
     34    public_addr: ""
     35    insecure_skip_verify: false
     36    labels:
     37      dc: "<dc>"
     38      type: "maas"
     

6. Add Teleport to /etc/hosts
   • sudo vi /etc/hosts
   • add an entry of 10.10.100.22 <Domain name of your teleport server> (what you made here)
   • 
   • Save and quit the file
7. Start the Teleport agent:
   • sudo systemctl enable teleport
   • sudo systemctl start teleport
