Tutorial: Start using Joe Bot for PostgreSQL query optimization
#
Step 1. Requirements- Set up Database Lab Engine (e.g., running on address https://dblab.domain.com) before configuring Joe Bot
note
Make sure the address used in
accessHost
is accessible from where you are going to run Joe Bot. - Prepare any Linux machine with Docker. See the official documentation on how to install Docker on Linux
#
Step 2. Configure communication channelsThere are two available types of communication with Joe:
- Web UI powered by Postgres.ai Console
- Slack
You can use both of them in parallel. If you can develop in Go language, feel free to implement more types of communication: see communication channels issues.
We need to define where to store the configuration file. We will use ~/.dblab/joe/configs/joe.yml
.
Configuration example:
mkdir -p ~/.dblab/joe/configs
curl https://gitlab.com/postgres-ai/joe/-/raw/0.10.0/configs/config.example.yml \ --output ~/.dblab/joe/configs/joe.yml
Then, configure ways of communication with Joe.
#
Step 2a. Set up Joe in Postgres.ai Console ("Web UI")If you don't need Web UI and prefer working with Joe only in messengers (such as Slack), comment out channelMapping: communicationTypes: webui
subsection in Jog config, and proceed to the next step.
Before configuring Web UI make sure you have a Postgres.ai account.
If you don't have a Postgres.ai account yet, see the guide on how to start working with Postgres.ai Console.
To configure Web UI:
First, get your
JOE_PLATFORM_TOKEN
. This token lets Joe Bot talk to Postgres.ai Platform to enable Web UI chat window, save the history of commands, and visualize query plans. In Postgres.ai Console, switch to proper organization and open theAccess Tokens
page. Save it to Joe config (platform: token
).Then, go to the
Joe instances
page in theSQL Optimization
sidebar section.Choose a project from the dropdown menu and press the
Add instance
button.Generate
Signing secret
. Put it in the configuration file (channelMapping: webui: <your channel name>: credentials: signingSecret
). We will add and verify the URL on the last step, so do not close the page.
#
Step 2b. Set up Joe bot in SlackIf you need to work with Joe bot in Slack, uncomment channelMapping: communicationTypes: slacksm
subsection in Joe config, and follow these instructions.
Configure a new Slack App in order to use Joe in Slack and add the app to your team Workspace.
Create
#db-lab
channel in your Slack Workspace (You can use another channel name).Choose From an app manifest option in popup.
Paste next yaml.
_metadata: major_version: 1 minor_version: 1display_information: name: Joe Bot description: PostgreSQL query optimization assistent background_color: "#2b2c30"features: app_home: home_tab_enabled: false messages_tab_enabled: false messages_tab_read_only_enabled: false bot_user: display_name: Joe Bot always_online: false oauth_config: scopes: bot: - chat:write - files:read - files:write - users:read - users.profile:read - channels:history - incoming-webhook - reactions:write - app_mentions:readsettings: event_subscriptions: bot_events: - app_mention - message.channels interactivity: is_enabled: true org_deploy_enabled: false socket_mode_enabled: true token_rotation_enabled: false
Press "Install App to Workspace".
Choose
#db-lab
channel.You will get "Bot User OAuth Access Token" which is required to run the Joe app.
Generate App Level token.
Go to the "Basic Settings" page and scroll down to "App-Level Tokens" section. Press "Generate Token and Scopes".
Fill in token name (e.g. "joe socket mode") and add scope
connections:write
You will get "App Level Token" which is required to run the Joe app in Slack SocketMode.
Now we have all tokens. Fill in "Bot User OAuth Access Token" and "App Level Token" in slacksm config section, and we are ready to run Joe Bot.
#
Step 3. Run Joe Bot containerLaunch Joe Bot container which immediately connects to the Database Lab instance(s) you've specified in the config file.
sudo docker run \ --name joe_bot \ --publish 2400:2400 \ --restart=on-failure \ --volume ~/.dblab/joe/configs:/home/configs:ro \ --volume ~/.dblab/joe/meta:/home/meta \ --detach \postgresai/joe:latest
To observe Joe logs use:
sudo docker logs -f joe_bot
Need you to reconfigure or upgrade, you can stop and remove the container any time using
sudo docker stop joe_bot
andsudo docker rm joe_bot
and then launching it again as described above.Make a publicly accessible HTTP(S) server port specified in the configuration to receive requests from communication channels Request URL (e.g., http://35.200.200.200:2400, https://joe.dev.domain.com).
Instead of working using insecure HTTP, you can set up NGINX with SSL enabled and open port 443, similarly as described in "Secure Database Lab Engine".
#
Step 4. Verify the configuration#
Step 4a. Finish the Web UI configurationReturn to the page of Joe configuration in the Console, enter the URL with the specific path
/webui/
. For example,https://joe.dev.domain.com/webui/
.Press the
Verify
button to check connection andAdd
the instance after the verification is passed.Choose the created instance and send a command.
#
Step 4b. Finish the Slack configurationInvite "Joe Bot" to "#db-lab" channel.
Send a command to the #db-lab channel. For example,
help
.
See available configuration options here.
