CLI Commands
Place scripts in a folder. After writing, tell the user they can run:
wmill generate-metadata- Generate .script.yaml and .lock fileswmill sync push- Deploy to Windmill
Do NOT run these commands yourself. Instead, inform the user that they should run them.
Use wmill resource-type list --schema to discover available resource types.
Bash
Structure
Do not include #!/bin/bash. Arguments are obtained as positional parameters:
# Get arguments
var1="$1"
var2="$2"
echo "Processing $var1 and $var2"
# Return JSON by echoing to stdout
echo "{\"result\": \"$var1\", \"count\": $var2}"
Important:
- Do not include shebang (
#!/bin/bash) - Arguments are always strings
- Access with
$1,$2, etc.
Output
The script output is captured as the result. For structured data, output valid JSON:
name="$1"
count="$2"
# Output JSON result
cat << EOF
{
"name": "$name",
"count": $count,
"timestamp": "$(date -Iseconds)"
}
EOF
Environment Variables
Environment variables set in Windmill are available:
# Access environment variable
echo "Workspace: $WM_WORKSPACE"
echo "Job ID: $WM_JOB_ID"
