I did a docker swarm update to add a mount with "--mount-add". I got an error that was cut off on the terminal. While I've solved this particular issue myself, how do I continue to get error messages in the future that appear here?
Is there a way to get that error either from docker service update command (that's not cut off) or from the local logs of the manager node (if the error likely occurred on worker nodes)

I am trying to stop a docker container and get the following error:
This happens randomly on occasion and it is very frustrating to have restart the docker service and relaunch all my containers.
Would anyone know what could be happening to cause this? As far I have seen or know, there has not been any changes made to the container since they have been launched, may some changes in the content of the data in the containers. Also if people need more information, I would be happy to provide.
FYI everything that I am doing I am doing as a root user.
ALSO -- ABSOLUTLEY CANNOT STOP THE DOCKER DAMON OR RESTART IT, THIS MUST BE RESOLVED WHILE KEEPING THE CURRENT CONTAINERS OPEN AND RUNNIN.
Trying to create sitecore 10 image using Docker on Windows 10 Enterprise locally but getting unhealthy containers. Please help me out as I have tried various steps that was updated in the forums.

Checked the following things:
docker-compose stop on Powershell.
docker-compose down on Powershell.
iisreset /stop on Powershell to make sure that the required ports are free.
docker-compose up -d on Powershell.
Stopped, removed the container and executed the command docker-compose.exe up --detach multiple times but no luck.
Check the .env file and make sure SITECORE_LICENSE has a value.
You may need to run the init.ps1 file.
Based on the logs now provided in the comments above, my suggestion would be to check the collection SQL connection string, to the shardsmanager database.
You can inspect the SQL container in docker for Windows and find the IP address of the SQL server. Connect to that using ssms and try connecting with the creds you have in current string.
Edit: looking again at the exception, it looks like it can't find the SQL server. Yet the CM server appears to not have a problem finding the same server. So compare the web/master/core connection string to the collection one. I'm guessing the SQL server portion will be different?
Can anyone help me make sense of the below error and others like it? I've Googled around, but nothing makes sense for my context. I download my Docker Image, but the container refuses to start. The namespace referenced is not always 26, but could be anything from 20-29. I am launching my Docker container onto an EC2 instance and pulling the image from AWS ECR. The error is persistent no matter if I re-launch the instance completely or restart docker.

Update from my Github issue: https://github.com/moby/moby/issues/33656
It seems like the DeepSecurity agent (ds_agent) running on a container with Docker can cause this issue invariably. A number of other users reported this problem, causing me to investigate. I previously installed ds_agent on these boxes, before replacing it with other software as a business decision, which is when the problem went away. If you are having this problem, might be worthwhile to check if you are running the ds_agent process, or other similar services that could be causing a conflict using 'htop' as the user in the issue above did.
Did you try running it with the --privileged option?
If it still doesn't run, try adding --security-opts seccomp=unconfined and either --security-opts apparmor=unconfined or --security-opts selinux=unconfined depending whether you're running Ubuntu or a distribution with SELinux enabled, respectively.
If it works, try substituting the --privileged option with --cap-add=NET_ADMIN` instead, as running containers in privileged mode is discouraged for security reasons.
I've been trying to set up an Continuous Delivery server with Bamboo. I've got everything going nicely up to the deployment. Bamboo builds and tests my C# project as it should.
Then I created a "deployment plan", installed docker and added the server capability to use docker, set up the docker tasks to build and deploy to dockerHub.
When I try to deploy, I get this error:
An error occurred trying to connect: Post http: //127.0.0.1:2375/v1.22/build ?buildargs=%7B%7D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&forcerm=1&memory=0&memswap=0&rm=1&shmsize=0&t=srgskiri%2Fresttest&ulimits=null : dial tcp 127.0.0.1:2375: connectex: No connection could be made because the target machine actively refused it.
01-mrt-2016 13:19:03 Failing task since return code of [C:\Program Files\Docker Toolbox\docker.exe build --force-rm=true --tag="srgskiri/resttest" C:\Users\Srg\bamboo-home\xml-data\build-dir\2129921-2195457] was 1 while expected 0
Now I think that it means that the bamboo 'object' that is calling the command to build, can't communicate with my docker engine/container.
First I thought it was because I didn't have docker-machine running, so I started it and ran the deploy, and still got this error.
This is what I have:
Server capability: path to docker
Docker task: building into an Image
Is there something I'm missing?
PS: Docker works perfectly on its own, both with docker UI or docker terminal. It's bamboo that can't interact with docker.
UPDATE: I didn't mention this, but I ran Bamboo in a Console, not as a service. Maybe thats the problem, that bamboo can't access docker out of console. I can't try this myself now because I can't install bamboo as a service. Keeps hanging if I try to start it as a service.
Will ask the bamboo support about it.
I figured it out... If u work on a Windows, Bamboo has to start the docker-machine itself.
So you have to add Command tasks to:
1) create a docker-machine (if u don't have any yet)
2) start it (if you start docker in bamboo, you can't access it in Windows and vice-versa)
only then you are able to use Docker in Bamboo on Windows.
I feel silly now
-EDIT- To use the Docker tasks after starting the docker-machine, you must also specify the Environment variables for the tasks (like DOCKER_TLS_VERIFY=1)
Otherwise you'll get the error mentioned above.
I am unable to run rabbitmq using marathon/mesos framework. I have tried it with rabbitmq images available in docker hub as well as custom build rabbitmmq docker image. In the mesos slave log I see the following error:
E0222 12:38:37.225500 15984 slave.cpp:2344] Failed to update resources for container c02b0067-89c1-4fc1-80b0-0f653b909777 of executor rabbitmq.9ebfc76f-ba61-11e4-85c9-56847afe9799 running task rabbitmq.9ebfc76f-ba61-11e4-85c9-56847afe9799 on status update for terminal task, destroying container: Failed to determine cgroup for the 'cpu' subsystem: Failed to read /proc/13197/cgroup: Failed to open file '/proc/13197/cgroup': No such file or directory
On googling I could find one hit as follows
https://github.com/mesosphere/marathon/issues/632
Not sure if this is the issue even I am facing. Anyone tried running rabbitmq using marathon/mesos/docker?
Looks like the process went away (likely crashed) before the container was set up. You should check stdout and stderr to see what happened, and fix the root issue.
"cmd": "", is the like'y culprit. I'd look at couchbase docker containers for a few clues on how to get it working.
