$ copilot svc deploy
What does it do?
copilot svc deploy takes your local code and configuration and deploys it.
The steps involved in service deploy are:
image.buildexists in the manifest:
- Build your local Dockerfile into an image
- Tag it with the value from
--tagor the latest git sha (if you're in a git directory)
- Push the image to ECR
- Package your manifest file and addons into CloudFormation
- Create / update your ECS task definition and service
What are the flags?
--allow-downgrade Optional. Allow using an older version of Copilot to update Copilot components updated by a newer version of Copilot. -a, --app string Name of the application. --detach Optional. Skip displaying CloudFormation deployment progress. --diff Compares the generated CloudFormation template to the deployed stack. --diff-yes Skip interactive approval of diff before deploying. -e, --env string Name of the environment. --force Optional. Force a new service deployment using the existing image. -h, --help help for deploy -n, --name string Name of the service. --no-rollback Optional. Disable automatic stack rollback in case of deployment failure. We do not recommend using this flag for a production environment. --resource-tags stringToString Optional. Labels with a key and value separated by commas. Allows you to categorize resources. (default ) --tag string Optional. The tag for the container images Copilot builds from Dockerfiles.
--no-rollback flag is not recommended while deploying to a production environment as it may introduce service downtime.
If the deployment fails when automatic stack rollback is disabled, you may be required to manually start the stack
rollback of the stack via the AWS console or AWS CLI before the next deployment.
--diff to see what will be changed before making a deployment.
$ copilot svc deploy --diff ~ Resources: ~ TaskDefinition: ~ Properties: ~ ContainerDefinitions: ~ - (changed item) ~ Environment: (4 unchanged items) + - Name: LOG_LEVEL + Value: "info" Continue with the deployment? (y/N)
copilot svc package --diff
Alternatively, if you just wish to take a peek at the diff without potentially making a deployment,
you can run
copilot svc package --diff, which will print the diff and exit.
