+# Docker Swarm Usage
+
+## Healthcheck
+
+The Docker Image includes a Healthcheck with the following options (Look at Dockerfile):
+
+--interval=30s: This option specifies the time interval at which the health check should be performed. In this case, the health check will be performed every 30 seconds.
+
+--timeout=10s: This option specifies the amount of time to wait for a response from the health check command. If the response does not arrive within 10 seconds, the health check will be considered a failure.
+
+--start-period=5s: This option specifies the amount of time to wait before starting the health check process. In this case, the health check process will begin 5 seconds after the container is started.
+
+--retries=3: This option specifies the number of times Docker should retry the health check before considering the container to be unhealthy.
+
+The CMD instruction is used to define the command that will be run as part of the health check. In this case, the command is "wget --quiet --tries=1 --spider http://localhost:3000/ || exit 1". This command will attempt to connect to http://localhost:3000/ and if it fails, it will exit with a status code of 1. If this command returns a status code other than 0, the health check will be considered a failure.
+
+Overall, this HEALTHCHECK instruction is defining a health check process that will run every 30 seconds, wait up to 10 seconds for a response, begin 5 seconds after the container is started, and retry up to 3 times. The health check will consist of attempting to connect to http://localhost:3000/ and will consider the container to be unhealthy if it is unable to connect.
