UI Instructions

Setup

Generating UI configs locally.

Some additional setup is required to generate local ui configs.

  1. First, on your local machine, add the following lines to your default ansible hosts file:

     [ui]
 localhost ansible_connection=local
 [services]
 localhost ansible_connection=local

    On Linux, this file should be in /etc/ansible/hosts, or an a Mac it may be in /usr/local/etc/ansible/hosts. Use ansible --help and check the -i INVENTORY, --inventory-file=INVENTORY help text to see where the default is on your machine.

  2. Next, again on your local machine, cd into this repo's host_vars directory and create a symlink to the group_vars environment of the services where you want your UI to connect, but name the link localhost.

So, if you want to generate your configs for the de-2 environment, you would do the following:

cd host_vars
ln -s ../group_vars/de-2 localhost

If you want your configs to point to gargery instead, do the following

cd host_vars
rm localhost
ln -s ../group_vars/gargery localhost

So, what does this do?

The first step is necessary so we don't have to include an inventory when running our play locally. The second step is necessary to populate default variables set in group_vars.

Also, it is no longer necessary to manually set your local IP address. Again, take a look in local_dev/ui.json, and you will see this line; "app_server_base_url": "http://{{ ansible_default_ipv4.address }}:8080"

Be sure to comment out the lines in /etc/ansible/hosts which do not apply.

OK!! GREAT!! How do I generate the configs?

ansible-playbook ui.yaml -K --tags "local_config" --extra-vars="@local_dev/ui.json"

Use --extra-vars "@vars_file.json" for configs using local service overrides. For example, if you are testing both the UI and Donkey locally, but want to use all other de-2 services:

ansible-playbook ui.yaml -K --tags "local_config" --extra-vars="@local_dev/ui.json" --extra-vars="@local_dev/donkey.json"

Updating the UI

There is only one playbook for deploying the UI. The group_vars files determine which Docker tag the playbook obtains the UI image from.

  • Be sure you have followed the instructions under Setting Up Your Accounts so that your ssh keys are setup between the server the wars are being deployed on.

    ansible-playbook -i inventories/... -K [-u ] ui.yaml

The -K will force a prompt for your sudo password. -i points to the inventory to use and -u indicates which user to ssh into the server as (optional).
