Troubleshooting Tips: Docker Context Deadline Exceeded error

Have you been facing the “Context deadline exceeded” error recently? Fortunately, our Support Engineers have a couple of troubleshooting tips to help you resolve the issue.

• To begin with, the WAIT_HOSTS option allows us to add the list of services on which the specific services returning the error depend in the docker-compose.yml file. In other words, adding the WAIT_HOSTS option to the docker-compose file under the environment section may resolve the error instantly.
• Alternatively, another option is to check whether the node is in drain state:

  docker node inspect --format {{.Spec.Availability}} node

  If so, we can update the state as seen below to resolve the Docker Context Deadline Exceeded error:

  docker node update --availability active node

  A node in the drain state tends to not allocate swarm mode resources like multi-host overlay network IP addresses to the node. Additionally, the swarm mode does not offer a messaging option between the swarm leader to the worker node requesting the IP address. This results in the Docker context deadline exceeded error. Fortunately, changing the status of the node resolves the issue.
• According to our Support Techs, another way to resolve the error is to verify the following port are open on both the machines:
  • • TCP/ UDP: Port 7946
    • TCP: Port 2377
    • UDP: Port 4789

  If not, we can use ufw as seen here to allow the ports:

  ufw allow 2377/tcp
• Finally, our skilled engineers recommend ensuring that the ENGINE VERSION of the nodes is the same.
