Running Flow Scripts Remotely

flow-runner.bash:

#!/usr/bin/env bash
echo "Running flow..."
DIR=$(dirname $0)
TOKEN_FILE="${DIR}/token"
TOKEN=$(cat "${TOKEN_FILE}")
if [ -z "${TOKEN}" ]; then
    ${DIR}/auth.bash
fi
FLOW=$1
if [ -z "${FLOW}" ]; then
    echo "missing parameter " 1>&2
    exit 1
fi
if [ ! -f "${FLOW}" ]; then
    echo "flow ${FLOW} does not exist" 1>&2
    exit 1
fi
echo "Flow: ${FLOW}"
NAME=$(basename "${FLOW}")
SCRIPT=$(cat "${FLOW}" | base64 -w0)
EXECUTION="{\"script\":\"${SCRIPT}\",\"name\":\"${NAME}\"}"
curl -H "Authorization: $TOKEN" -d "${EXECUTION}" https://<my-workspace-name>.cloudomation.com/api/latest/execution
echo ""

This helper script requires auth.bash to be in the same directory. Please find more information in the article about Authentication.

You can execute the helper script and pass the path to a local flow script as first parameter:

bash:

$ ./flow-runner.bash hello.py
Running flow...
Flow: hello.py
{"id": 1234}

You can also use the helper script as shebang  in your script and directly execute it:

hello.py:

#!/path/to/your/flow-runner.bash
import flow_api
def handler(system: flow_api.System, this: flow_api.Execution):
    return this.success('hello world')

bash:

$ chmod +x hello.py
$ ./hello.py
Running flow...
Flow: ./hello.py
{"id": 1235}
