containers

问题 I am running several LXC containers on Oracle Linux (host) and running EBS application inside those containers. Now I have more than 10 containers on every 5 hosts. I am looking for a solution for managing these containers. The research told me that Kubernetes is a solution for managing containers and perform several other activities with it like autoscaling ..etc. But Kubernetes works with LXD for lxc containers. Is there any way through which I can manage lxc container directly with

问题 I have deployed a container group with just one container in it, with the restart policy as Never. I want to run this container again, but with different environment variables. I see ways to do this in powershell and azure cmdlets, but the Azure .net SDK is not very clear on how this can be achieved. Does anyone have any pointers on how this can be achieved with the Fluent API? This will be useful for me, since the image need not be pulled again, just the container instance restarted. 回答1: I

问题 I am currently looking for container that provides some inserting (insert or push_back) and some removing (erase, pop_back is not sufficient) methods, and that does not invalidate iterators nor pointers when calling these two methods. More clearly, I want a set of elements where I can add an element (I do not care where), and where I can remove any element (so I do care where). In addition, I would have external pointers to specific elements, and I want them to remain valid if I add or remove

问题 I tried a column with an aligned icon but it didn't display correctly If anyone has any idea to help. It would be greatly appreciated. Thank you This is my code that i tried List<Widget> temp = []; listAirline.map((airline) { listAirlineName.map((item) { if (airline.name == item) { temp.add( Column( children: <Widget>[ Container( height: 20, decoration: BoxDecoration( color: Colors.white, borderRadius: BorderRadius.all(Radius.elliptical(100.0, 60.0)), ), child: Image.asset( "images/Airlines/"

问题 If I deploy an image built by choosing Alpine Linux as the base image on my Ubuntu machine (which acts as the host OS - where Docker is installed), will there be two kernels at play here - one from Ubuntu and another one from Alpine? I read that Docker containers will share the host Kernel, so I'm bit confused here. If I login to a running container and issue another command, will this be another process from the perspective of the host OS? Or will this be another thread? From the perspective

问题 I am attempting to push an image of a windows container to a "local" repository on a Windows VM, which has it's own IP address. So when I create the registry on my VM, I can view the repository list on my local machine by going to the ipaddress:5000 just fine. However, when I try to push an image to the registry it shows the layers to be pushed but at the bottom it says received unexpected HTTP status: 500 Internal Server Error. This isn't a problem when I switch to Linux containers. I can

问题 Is it considered a secure practice to run root privileged ENTRYPOINT ["/bin/sh", entrypoint.sh"] , that later switches to non-root user before running the application? More context: There are a number of articles (1, 2, 3) suggesting that running the container as non-root user is a best practice in terms of security. This can be achieved using the USER appuser command, however there are cases (4, 5) when running the container as root and only switching to non-root in the an entrypoint.sh

问题 When reading the source code of docker1.8, I find that reexec.Init() appears in docker.go , dockerinit.go and some test files. If reexec has registered functions, then reexec.Init() will return true so that in docker.go the process will return. From the README.md of package reexec : The reexec package facilitates the busybox style reexec of the docker binary that we require because of the forking limitations of using Go. So what's the purpose of using reexec.Init() ? Is the only purpose of
