These error codes may be returned when using the docker provisioner.

DOCKER_NOT_INSTALLED

• Caused by: Running the docker command failed because Docker is not installed, or the docker executable is not available on the PATH.
• Solution: Install Docker and ensure the docker command is available on the PATH of the machine running Flyway.

DOCKER_NOT_RUNNING

• Caused by: The docker command could not connect to the Docker daemon.
• Solution: Start Docker (or Docker Desktop) and ensure the daemon is running before retrying.

DOCKER_EULA_NOT_ACCEPTED

• Caused by: Provisioning a SQL Server or Oracle container without setting iAgreeToTheDBVendorsEula to true, which Flyway requires to confirm you accept the database vendor's EULA. See EULA acceptance.
• Solution: Set iAgreeToTheDBVendorsEula = true in the docker resolver configuration to confirm acceptance.
