I am trying to create a basic web page with docker-compose
This is my yml file
identidock:
build: .
ports:
- "5000:5000"
environment:
ENV: DEV
volumes:
- ./app:/app
When I run
docker-compose up -d
it shows
Starting identidock_identidock_1 ... done
But if I check images
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

It is obvious that new image has not been created.If I to http://localhost:5000/,
I got
Firefox can’t establish a connection to the server at localhost:5000.
This is docker ps -a output

Why?
The container may not have started. Check docker-compose ps. If the containers listed are not in Up state, then you can use docker-compose logs identidock to view the logs.

I'm trying to setup Kafka locally and facing an issue. Whenever I run docker compose up, all containers are up correctly. After sometime, the broker container stops running for some reason. There is no error in the container logs.
Below is the status of all docker containers:

All I want is a single node Kafka cluster with Schema Registry up and running locally. Any pointers are appreciated.
137 exit code is memory related.
If all you want is Kafka and the Schema Registry, remove KSQLDB stuff, REST Proxy, and DataGen containers
I'd also suggest using a later image tag, such as 7.3.1
I want to run container and receive error:
docker run -ti --rm grafana/promtail:2.5.0 -config.file=/etc/promtail/config.yml
docker: Error response from daemon: mkdir /var/lib/docker/overlay2/0cad6a6645e2445a9985d5c9e9c6909fa74ee1a30425b407ddfac13684bd9d31-init: no space left on device.
At first, I thought I have a lot of volumes and images cached. So I clean docker with:
docker prune
docker builder prune
But in a while, the same error occur. When I check my Docker Desktop configuration, I can see I am using all available disk size for images:
Disk image size:
59.6 GB (59.5 GB used)
I have 13 images on my system and together its less than 5GB:

I am new to MacOS and cannot determine what take all my space and how to clean all that space and where are all that data stored on system?
What does "in use" mean and how can I get that info from the CLI?

It indicates if the image is used by a container (running or already stopped).
You cannot get this via the CLI using docker images, but listing the containers docker ps -a you can see the associated image.
New to kubernetes. I was following a tutorial on kubernetes the other day. I forgot what I was doing. Running docker ps shows many containers of k8s*.

I also tried stopping the containers using docker stop. It stopped but few seconds later, the containers started again.
I also ran minikube delete but it only deleted minikube. The command docker ps still showed the containers.
I'd like to start from beginning again.
Don't try to delete pause containers.
k8s.gcr.io/pause:3.1 "/pause"
You can bring multiple containers in a k8s pod and they share same network namespace.
The pause containers are meant to be a way to share network namespace.
That's how the k8s pod is created.
For more info, please go through this.
If you want to reset your cluster, you can first list all namespaces using kubectl get namespaces, then delete them using kubectl delete namespaces namespace_name.
However, you can't delete the namespaces default, kube-system, and kube-public as those are protected by the cluster. What you can do is remove all Pods from the default and kube-public namespace using kubectl delete --all pods --namespace=default; kubectl delete --all pods --namespace=kube-public. You shouldn't touch the kube-system namespace as it contains resources that are mandatory for the cluster to function.
You can try deleting the files using the below commands:
kubectl delete -f <file location>
The file which you installed using:
kubectl apply -f <file location>
you can remove all the tags associated with it using:
istioctl tag remove <profile>
Note: You can refer manifests/profiles for referring the profiles
My situation is similar with you. Forgot what I did, then finding out many *k8s* containers running in docker. Which once deleted, will be started again automatically.
Uncheck Docker Desktop -> Settings -> Kubernetes -> Enable Kubernetes works for me. Hope that helps.
I follow the official tutorial of deploying docker services https://docs.docker.com/get-started/part5/#add-a-new-service-and-redeploy, in the first time i tried this the containers was running as expected but after that the containers shutdown and restarting (i notice that using the visualizer service provided by docker )
and when i execute the command :
docker stack ps getstartedlab
NAME DESIRED STATE CURRENT STATE
ERROR
getstartedlab_web.1 Running Preparing 2 seconds ago
\_ getstartedlab_web.1 Shutdown Failed 4 minutes ago

i read in this post https://github.com/docker/machine/issues/3747 that the problem came from the firewall that may block the icmp, i tried to ping docker.com and i had 100% loss packet but when i ping google.com it's ok with no loss packets.
the result of docker ps --all is :
