# Update App With Spec Doctl
doctl {{[a|apps]}} {{[u|update]}} {{app_id}} --spec {{path/to/spec.yml}} import subprocess
# Update App With Spec Doctl
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"doctl",
"a",
"u",
"<app_id>",

Pro Tip
Validate your YAML schema beforehand to avoid deployment failures.
Command Builder
Tune the command before you copy it

Power User Variants
Optimized versions
doctl apps update app_id --spec path/to/spec.yml --force Force the update, bypassing validation on the spec.

Common pitfalls
Error: invalid spec file
Solution: Ensure the spec file adheres to the necessary schema.
