Slack Workspace Preparation

   1. Choose any name for the app
   2. Choose your workspace where you want to install the app in
   3. From the left-side menu, choose OAuth & Permissions
   4. We need to give our application the permission to do actions in the workspace, i.e. send/read messages, create channels,...etc. Go to Scopes, choose chat:write (to send messages).
   5. Choose Install App to Workspace. Now in your workspace, you will find in your recent apps, your new app.

Application Preparation

1. Clone the repo

git clone https://github.com/scimma/hop-slack-app

2. In the repo local directory, run:

python setup.py install

try: Hop-slack --version

3. Prepare Slack configurations file: The file is organized into three sections:
   1. [SLACK_PROPERTIES] : It contains slack's token, username, icon_url,...
   2. [TOPIC_CHANNEL_MAPPING] : It contains the corresponding channels for the topics
   3. [GENERAL] : It contains general configurations, i.e create channel for topic if it does not exist. A sample for the file:

   [SLACK_PROPERTIES]
   SLACK_TOKEN= xoxb-*****
   SLACK_USERNAME= Hop_SlackBot
   [TOPIC_CHANNEL_MAPPING]
   test= Testing
   gcn= GCN_Circular
   [GENERAL]
   DEFAULT_CHANNEL = general
   CREATE_CHANNEL = true
   

4. Run Hop-slack: hop-slack subscribe -b <Broker_URL> -S <Slack_Config_File>

In case you have a server container running as:

docker run -p 9092:9092 -v /tmp/kafka-logs:/tmp/kafka-logs -v /tmp/shared:/root/shared --hostname localhost hop/server --noSecurity

You can have a slack command as

hop-slack subscribe -b kafka://localhost:9092/test -S /mnt/config_files/slack_config.cfg -e

Where:

• -b or --broker-url : Broker URL
• -e or --earliest : For posting the earliest received messages
• -S or --slack-config-File : Path to slack's configuration file
• -j or --json : Set the formate of the received message from broker
• -F or --config-file : Path to client'c configuration file
• -X or --config : Set client configuration via prop=val. Can be specified multiple times.
