Issues when connecting to Memgraph

docker run memgraph 

While this command will start a Memgraph instance, not publishing the port will cause problems when trying to connect to the database via Memgraph Lab, mg_client or mgconsole. To avoid this, you should publish the container's port to the host using the -p flag and by specifying the port:

docker run -p 7687:7687 memgraph 

Issues with connecting mg_client to the database

docker run -it --entrypoint=mg_client memgraph --host HOST --use-ssl=False 

Although unlikely, sometimes there are issues with connecting mg_client to the Docker Container’s IP address because it is running on a custom IP rather than localhost. This problem is most often accompanied with the following error:

Connection failure: Couldn't connect to! 

To fix this issue, just replace HOST from the first command with host.docker.internal. To find out more about networking in Docker, take a look at this guide.

Find the IP address of a Docker Container

Although unlikely, some users might experience minor difficulties after the Docker installation. Instead of running on localhost, a Docker container for Memgraph may be running on a custom IP address. Fortunately, that IP address can be found as follows:

1. Determine the ID of the Memgraph Container by issuing the command docker ps. The user should get an output similar to the following:

CONTAINER ID    IMAGE       COMMAND                  CREATED
9397623cd87e memgraph "/usr/lib/memgraph/m…" 2 seconds ago

At this point, it is important to remember the container ID of the Memgraph Image. In our case, that is 9397623cd87e.

2. Use the this ID to retrieve the IP address of the Container:

docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' 9397623cd87e 

The command above will yield the IP address that should be used when connecting to Memgraph via Memgraph Lab, mgconsole or mg_client as described in the querying section. Just replace HOST from the following command with the appropriate IP address:

docker run -it --entrypoint=mg_client memgraph --host HOST --use-ssl=False
