**To update a service pipeline**

The following ``update-service-pipeline`` example updates a service pipeline to a new minor version of its service template. ::

    aws proton update-service-pipeline \
        --service-name "simple-svc" \
        --spec "file://service-spec.yaml" \
        --template-major-version "1" \
        --template-minor-version "1" \
        --deployment-type "MINOR_VERSION"

Output::
