| # Vertex AI Gemini Pro Slack bot example | ||
|
|
||
| A Slack chat bot that uses the Gemini 1.0 Pro Vision model. It can accept images and text from Slack. | ||
|
|
||
| ## Deploying | ||
|
|
||
| 1. Navigate to Slack settings, `Tools & Settings > Manage apps`. | ||
| 2. Click on `Build` in the top right corner. | ||
| 3. Click on `Create new app` and select `From manifest`. | ||
| 4. Copy the contents [slack-manifest.yaml](slack-manifest.yaml) into the text box. | ||
| 5. Proceed with creation of the Slack application and install it to your workspace. | ||
| 6. You should now be able to view application credentials. Take the `App ID` and `Signing Secret` and place them in `terraform.tfvars` (`slack_app_id` and `slack_signing_key`). | ||
| 7. Next click on `OAuth & Permissions` and take the `Bot User OAuth Token` and place it in `terraform.tfvars` (`slack_token`). | ||
| 8. You can now run `terraform apply` to deploy the bot. After deployment, you should see the Cloud Run Json2Pubsub URL in the output. | ||
| 9. In Slack app settings, click on `Event Subscriptions` and replace the `Request URL` with the URL from the previous step. | ||
| 10. In Slack, create a channel and add the bot to it (channel settings, `Integrations > Add an app`). | ||
| 11. You can now discuss with the bot via private messages or tagging it in a channel! | ||
|
|
||
| ### Example Terraform connfiguraiton | ||
|
|
||
| Example `terraform.tfvars` file: | ||
|
|
||
| ```hcl | ||
| project_id = "<your-project-id>" | ||
| region = "europe-west1" | ||
| slack_token = "xoxb-...." # Slack OAuth token for workspace | ||
| slack_signing_key = "8e................02f" # Slack signing key | ||
| slack_app_id = "A........L" # App ID | ||
| ``` | ||
|
