'Error response from daemon: network myapp not found

I am trying to create a container in a multihost network but while creating I am getting this error:

Error response from daemon: network myapp not found

Here myapp is the name of overlay network which i have created. The command I am using is:

sudo docker run --rm -it --name=test_cont --net=myapp ubuntu bash

docker

Docker networks are scoped for different access. Your myapp network is an overlay network scoped to the swarm.

That means you can only use it at swarm level - docker service create --network myapp will work fine, because services are at swarm level too.

You can start a container with docker run on a swarm, but it will only run locally on the node where you run the command on, so it can't see swarm networks.

I started getting this error after doing a docker system prune.

docker network ls showed my network:

NETWORK ID          NAME                DRIVER              SCOPE
pgl0gb0mbwql        myapp               overlay             swarm

But deploying the stack would give error like:

failed to create service myapp_database: Error response from daemon: network myapp not found

Then I asked myself the most important debugging question there is: Have you tried turning it off and on again?

I restarted my docker daemon and the network was deleted for real. I was then able to re-create it and everything started working again.

Remove container (not Image) and then run again:

docker compose up

Solution 4:^[4]

In my case, it did not delete the network even though it was in swarm mode, but if I created it again, it threw an error because there was already a network with that name. I had to restart the docker service, these were the steps:

docker network rm myapp                   #launch the error that the network did not exist
sudo systemctl restart docker.service     #restart the docker service
docker network ls                         # not shows network.

Solution 5:^[5]

Suppose that you connect myapp_net network to app_container then:

docker network disconnect -f myapp_net app_container # Force disconnect
docker network create myapp_net # Create docker network again
docker network connect myapp_net app_container # Connect docker network again

It could resolve your problem.

In my case error was because of naming issue, recheck your network name in docker and give the same in your command.

steps I followed: (for windows)

stop all the docker service

docker compose down

close docker GUI and restart the docker

go to taskbar and click on show hidden icons --> right click it --> docker restart.

open terminal and go to the directory where the docker file is present (.yml)
run all the docker services using the cmd :

docker compose up

open new terminal and run : check the network name

docker network ls

copy the name and paste it in your network name section in your command.

docker run --tty --network < here your network name > confluentinc/cp-kafkacat kafkacat -b kafka: -C -s key=s -s value=avro -r http://schema-reg: -t postgres.public.shipments

Solution 7:^[7]

in my case i had to:

docker system prune
systemctl restart docker.service

to make it work again...
