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'm new to using Docker (never used it before) and I'm running into these errors:
I installed the Docker for Windows and following the steps on this
tutorial, but Docker Desktop doesn't load up for me at all.
I tried to run the docker pull hello-world command but I'm getting the error: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.
How do I fix this? Thanks
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 build a docker image in windows using linux based containers. Now when I try to run it, it runs successfully on 127.0.0.1:5000. But when I try to test it in the browser, it does not work.
I run docker images to see the built images. The image gaitimg:V1 which I want to run on localhost, is present there.
I try to run it using the following command:
docker run -p 5000:5000 gaitimg:V1 .
It runs successfully! However, I cannot run it in the browser in Windows.
Thanks to the bitcoin.stack community I have successfully launched a bitcoind docker with an external volume which has the block data
Currently its in 100% sync but I am facing an issue to get information using bitcoin-cli I need to run bitcoind -reindex and then add txindex=1 into bitcoin.conf
As I pulled the docker image from docker hub I do not have any control over its docker file and I have 140GB+ blockchain data that I do not wanna discard and start over
How do I run --reindex on an docker container ?
While your container is running you can run docker exec -it <mybitcoindcontainer> /bin/sh. This should give you a shell inside your running container. You can then run your choice of commands at the shell prompt.
New to docker and I'm using Windows 7 SP1. It looks like docker is running fine in my machine as I have tried running hello-world by command docker run hello-world as instructed in the tutorial and got expected result. Now all I'm trying to do is create a docker image for a .net core console app. My app built and ran. but while building docker image by command docker build -t myapp . I get the below error
error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.30/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&c

Below my Dockerfile
FROM microsoft/dotnet:1.1-runtime-nanoserver
WORKDIR /DotNetConsole
COPY /bin/Debug/netcoreapp1.1/publish/ .
ENTRYPOINT ["dotnet", "DotNetConsole.dll"]
I could get around this problem by starting the "Docker QuickStart Terminal" installed with the docker tools, and running the commands for building the docker images from there.
If I used GIT BASH instead of the Docker QuickStart Terminal to execute the commands, I would get this kind of error. So it seems that if the commands are not executed from the Docker terminal itself, these errors show up.
