    • createLocalstackContainer

      public static Container createLocalstackContainer​(java.lang.String externalHostName, boolean pullNewImage, boolean randomizePorts, java.lang.String imageTag, java.util.Map<java.lang.String,​java.lang.String> environmentVariables, java.util.Map<java.lang.Integer,​java.lang.Integer> portMappings)
      It creates a container using the hostname given and the set of environment variables provided
      Parameters:
      externalHostName - hostname to be used by localstack
      pullNewImage - determines if docker pull should be run to update to the latest image of the container
      randomizePorts - determines if the container should expose the default local stack ports or if it should expose randomized ports in order to prevent conflicts with other localstack containers running on the same machine
      environmentVariables - map of environment variables to be passed to the docker container

    • getRunningLocalstackContainer

      public static Container getRunningLocalstackContainer()
