Spin-to-Slack

Spin-to-Slack is a sample application demonstrating how to use configuration data in Fermyon Spin. For detailed walk-through consider reading the corresponding blog post at: https://www.thorsten-hans.com/master-configuration-data-in-fermyon-spin.

How to run Spin-to-Slack

Either Docker is required (to run HashiCorp Vault) or you must ensure your Spin application can access an instance of HashiCorp Vault that runs somewhere else.

HashiCorp Vault

docker run -d -e VAULT_DEV_ROOT_TOKEN_ID=foobar \
 -e VAULT_SERVER="http://127.0.0.1:8200" \
 -p 8200:8200 vault

# Install vault CLI (macOS shown here with Homebrew)
brew install vault

# Set Vault URL and token as env vars
# Alternatively, you can provide the token when using vault CLI
export VAULT_ADDR='http://0.0.0.0:8200'
export VAULT_TOKEN=foobar

# Store slack_webhook_url in vault
vault kv put secret/slack_webhook_url value="YOUR slack webhook url"

Run Spin-to-Slack

export SPIN_APP_CHANNEL="#blog"
export SPIN_APP_IS_MARKDOWN="true"

# 3. Start the Spin application
spin build --up --follow-all --runtime-config-file vault.toml
