slack

Simple Workflow Example

This example runs the slack-channel.yaml.

Explanation

This folder contains a demo example of a workflow that creates a Slack channel, adds a default user to that Slack channel, and send an initial message to the channel. The workflow file showcases the following features:

• Running a simple job with a set of dependent steps
• Variable references within step arguments -- each subsequent step in a workflow can call .steps.<step_id>.outputs to access output arguments

While the main.go file showcases the following features:

• Using an existing integration called SlackIntegration which provides several actions to perform
• Providing a custom workflow file (as the workflow file needs to be populated with an env var $SLACK_USER_ID)

How to run

Navigate to this directory and run the following steps:

1. Make sure you have a Hatchet server running (see the instructions here). After running task seed, grab the tenant ID which is output to the console.
2. Set your environment variables -- if you're using the bundled Temporal server, this will look like:

cat > .env <<EOF
SLACK_USER_ID=<TODO>
SLACK_TOKEN=<TODO>
SLACK_TEAM_ID=<TODO>

HATCHET_CLIENT_TENANT_ID=<tenant-id-from-seed-command>
HATCHET_CLIENT_TLS_ROOT_CA_FILE=../../hack/dev/certs/ca.cert
HATCHET_CLIENT_TLS_CERT_FILE=../../hack/dev/certs/client-worker.pem
HATCHET_CLIENT_TLS_KEY_FILE=../../hack/dev/certs/client-worker.key
HATCHET_CLIENT_TLS_SERVER_NAME=cluster
EOF

1. Run the following within this directory:

/bin/bash -c '
set -a
. .env
set +a

go run main.go';
