I have installed Dockers on my Synology DS. Then I downloaded the Eclipse Che image.
When I start the image, i keep seeing the following error in the logs.
!!! Docker socket (/var/run/docker.sock) hasn't be mounted inside the container. Verify the syntax of the "docker run" command.
The following are screenshots of the configuration of for the image. How do I get the container image going? Any help is fixing this problem will be much appreciated.
What Che image are you trying to run?
Last version, which supported docker deployment was Che 6. Current version is 7.x, but since 7.x support of docker has been dropped and Che is supposed to run on k8s clusters.
But even if we are talking about Che6, Che server (the image you are probably trying to run) needs to have capability to connect to host docker daemon to spawn new containers (each workspace will be its own new container).
This is why, when starting che, you need to mount /var/run/docker.sock.
So the usual comand to start che in Che6 days was something like this:
docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock -v <path>:/data eclipse/che start

I have installed docker on redhat/centos server. docker services are running fine but how I can install or build cassandra/scylla image on docker. my server is not connected with internet so while building cassandra/scylla image or run then getting below error "Unable to find image" with timeout exception.
Can anyone help how to build cassandra/Scylla docker image without internet?
Thanks.
Once you download the image though, it is very simple to take it offline and load it into an offline system using docker save to export the image as a file, and docker load to import the image back into docker.
The problem does not seem to be related to Apache Cassandra or Scylla.
You do need access to Docker hub to download the relevant image for the first time, for example when running docker run hello-world
Once you solve that, you can move to run Apache Cassandra or Scylla with, for example with
docker run --name some-scylla -d scylladb/scylla
I created a sample microservice application with war file. After that I installed Docker tool box. Then I created sample Dockerfile and trying to build image using Docker toolbox quick start terminal.
I changed directory to project root directory, and ran the following command:
docker build -t "dockerDemo" .
And getting error like Docker daemon is not running.
And also I run the following commands:
docker run hello-world
docker-machine ls
I am getting following results screens.
I am now just started with containers and Docker concept. How can I solve this?
According to your screenshots, it's a pretty common issue. Unfortunately the only solution is to remove the vm and recreate it. You can find more details in this issue.
$ docker-machine rm default
$ docker-machine create --driver virtualbox default
Delete de Docker toolbox virtualbox vm. It is usually named "default". Close and open again the docker console, it will create again the vm automatically. Then try again.
I have a strange problem:
I created a docker-container (debian image) and installed an apache-server. However when i restart the container, everything else is there but the server is not starting on bootup. I added apache2 with the systemctl command, but still it is not working. I don't know if this is a docker thing or a debian problem.

On docker image you have not to deal with systemd to start a program. Instead take a look at the Dockerfile's directives ENTRYPOINT and CMD (https://docs.docker.com/engine/reference/builder/#entrypoint and https://docs.docker.com/engine/reference/builder/#cmd).
If you want to have an apache inside a container there are some images available on docker hub. You can look to the Dockerfile to have an idea on how it works.
The docker version is 0.10.0, the linux system is Centos6.5.
Three containers have been running in the system for 3 months in OpenStack. I put the nova-compute service in a container.
I found that nova-compute container didn't work recently.
I delete the json.log of the container when I found the log is 3GB,
but it still does not work.
I try to delete,stop,restart the container,restart the system,it's still the same.
dockerctl 6a82f22d2dad
lxc-attach:failed to get the init pid
docker rm -f 6a82f22d2dad
Error:
2015/08/11 08:51:32 Error:failed to remove one or more containers
docker stop 6a82f22d2dad
Error:failed to stop one or more containers
When running docker ps, the compute container works well.
Now I could not get other information because I can't connect the remote machine. Has anybody the same problem?
Redhat has come right out and stated that they do not support Docker on CentOS 6.x systems.
If you can, I suggest you upgrade to CentOS 7 and the latest Docker version.
You can find more info about CentOS 6.x Docker support here
