Depends on the container. e.g. if it’s a vector, after modifying the container all iterators can be invalidated. However, if it’s a list, the iterators irrelevant to the modified place will remain valid. A vector’s iterators are invalidated when its memory is reallocated. Additionally, inserting or deleting an element in the middle of a vector … Read more
A Docker container in a Docker container uses the parent HOST’s Docker daemon and hence, any volumes that are mounted in the “docker-in-docker” case is still referenced from the HOST, and not from the Container. Therefore, the actual path mounted from the Jenkins container “does not exist” in the HOST. Due to this, a new … Read more
Alternatively, if you do not wish to push to a repository: Export the container to a tarball docker export <CONTAINER ID> > /home/export.tar Move your tarball to new machine Import it back cat /home/export.tar | docker import – some-name:latest
Any random-access container (like std::vector) can be sorted with the standard std::sort algorithm, available in the <algorithm> header. For finding the median, it would be quicker to use std::nth_element; this does enough of a sort to put one chosen element in the correct position, but doesn’t completely sort the container. So you could find the … Read more
It is possible the / is interpreted as an option by the CMD Windows shell. Try first a docker-machine ssh default, in order to open an ssh session in your VM. From there try the docker run again: docker run -v /c/Users/phisch/dev/htdocs:/var/www phisch:dev As commented by thaJeztah in issue 18290: You could consider using docker-compose; … Read more
You can find tons of example of WindowsServiceCore-based applications in StefanScherer/dockerfiles-windows You need to write a Dockerfile (like for instance diskspd/Dockerfile where you copy/unzip/install the application you need.

Pass a reference to the Bar object, like so: class Foo(object): def __init__(self): self.text = “Hello World” # has to be created first, so Bar.__init__ can reference it self.bar = Bar(self) class Bar(object): def __init__(self, parent): self.parent = parent self.newText = parent.text foo = Foo() Edit: as pointed out by @thomleo, this can cause problems … Read more
To make an Image fill its parent, simply wrap it into a FittedBox: FittedBox( child: Image.asset(‘foo.png’), fit: BoxFit.fill, ) FittedBox here will stretch the image to fill the space. (Note that this functionality used to be provided by BoxFit.fill, but the API has meanwhile changed such that BoxFit no longer provides this functionality. FittedBox should … Read more
Docker creates .dockerenv and .dockerinit (removed in v1.11) files at the top of the container’s directory tree so you might want to check if those exist. Something like this should work. #!/bin/bash if [ -f /.dockerenv ]; then echo “I’m inside matrix ;(“; else echo “I’m living in real world!”; fi
Question #1: why is NaN found in a container when it’s an identical object. From the documentation: For container types such as list, tuple, set, frozenset, dict, or collections.deque, the expression x in y is equivalent to any(x is e or x == e for e in y). This is precisely what I observe with … Read more
