V3 to V4 Migration Guide

General

Bump of minimum terraform version to 1.1.5 or newer. This is done as part of introducing the new terraform-plugin-framework to develop this provider.

docker_container

Reworked handling of stopped containers: If a container is stopped (or exists for some other reason), Terraform now correctly shows a change on plan and restarts the container on apply. To trigger the change, the must_run attribute is exploited. must_run defaults to true and when a container is in a not running state, the provider sets must_run to false to trigger a state change. This fixes the cases where a stopped container gets deleted during a plan

• Fixes Ports on stopped container force replacement bug (https://github.com/kreuzwerker/terraform-provider-docker/issues/77)

docker_network

Removed attributes:

• check_duplicate

docker_service

New attribute:

• networks_advanced.id

Deprecated attribute:

• networks_advanced.name: Replaced by id attribute to make it clear that the docker_network.id needs to be used to prevent constant recreation of the service
