containers

The problem description I have a Docker image, which is being executed with volume mounting options a large number of times. It is built in a way so that the default user does not have root permissions. However I need to make sure that when I mount the volume it is being mounted as root and not as the current working user because of security concerns. (The current working non-root user must not be allowed to delete any files inside the mounted volume.) Example From the host machine: docker run -it -v /path/to/mount:/container/mounting/path image-name Inside the container current-user@docker

I need a way to quickly access data in a container. So I remember iterator of that data position. Container maybe modified (elements added and removed) after that, but if I use container type that does not invalidate my iterator (like std::map or std::list ) I am fine. Also my data may not be in the container (yet), so I set an iterator to container.end() to reflect that. Which standard container guarantees that end() would not change when elements added and removed? So I can still compare my iterator to the value returned by container.end() and not get false negative. 23.2.4/9 says of

i have 2 images on my stage underneath an overlay image of 2 frames. The user can drag each image as if they were positioninng each image inside a photo frame. The problem i have is the yoda image in this example can overlap and appear inside the darth vader frame on the left (and vice-versa), as shown here: jsfiddle here: http://jsfiddle.net/vTLkn/ Is there a way of placing the images inside some form of container or rectangle to stop this so they cannot appear inside another 'frame'? The final page could end up having up to 5 or 6 frames and images with each image able to be scaled up or

I need something not visible in page, something that don't have any borders and something that doesn't affect page rendering at all. I need this for a mass hiding or showing things inside, like document.getElementById("asd").innerHTML = "blah bla blah and some buttons and etc"; I want it's tag borders to not be shown on the page or changed the rendering at all. For example, I want the rendered result to be same for: <div> asd <input type = "button" value = "dsa" /> <table> <tr> <td>zxc</td> </tr> </table> qwe </div> and: <div> asd <something id = "asd"> <input type = "button" value = "dsa" />

I am using the embeddable EJB container of WebSphere 8 to write some unit tests for my EJBs with JUnit4. My IDE is the RAD 8. Here is my simple test code snippet: Map properties = new HashMap(); properties.put(EJBContainer.PROVIDER, "com.ibm.websphere.ejbcontainer.EmbeddableContainerProvider"); EJBContainer ec = EJBContainer.createEJBContainer(properties); I get a NoClassDefFoundError: java.lang.NoClassDefFoundError: com/ibm/ejs/ras/hpel/HpelHelper at com.ibm.ejs.ras.RasHelper.getThreadId(RasHelper.java:1760) at com.ibm.ejs.ras.RasEvent6$1.initialValue(RasEvent6.java:101) at java.lang

I am trying to docker exec a container that is built from scratch (say, a NATS container). Seems pretty straight-forward, but since it is built from scratch, I am unable to access /bin/bash , /bin/sh and literally any such command. I get the error: oci runtime error (command not found, file not found, etc. depending upon the command that I enter). I tried some commands like: docker exec -it <container name> /bin/bash docker exec -it <container name> /bin/sh docker exec -it <container name> ls My question is, how do I docker exec a container that is built from scratch and consisting only of

First of all, I'm using Hadoop-2.6.0. I want to launch my own app master on a specific node in a YARN cluster in order to open a server on a predetermined IP address and port. To that end, I wrote a driver program in which I created a ResourceRequest object and called setResourceName method to set a hostname, and attached it to a ApplicationSubmissionContext object by calling setAMContainerResourceRequest method. I tried several times but couldn't launch the app master on a specific node. After searching code, I found that RMAppAttemptImpl invalidates what I've set in ResourceRequest as
