How to set the shared drives in Docker for Windows? I am using the latest version 18. Stable and Edge. My settings screen is shown below. It's missing some options like Shared Drives, Advanced and Network, which are shown in the second image. Why am I missing these options?
Shared Drives with Docker for Windows
Because if you are using Docker on WSL 2, there is no such option, but you can directly attach volumes from filesystem with docker run -v c:\...\your-folder:/mount ... without specifying it in docker settings.
ok i am able to run a docker image by creating docker file and access it. Issue is how to do i code and share files between linux container and IDE( visual code). I see every one docker desktop ( on google search shared folder shows up in settings page) but mine have general resources command line kubernetes and no shared folder inside of these tabs also.
Prefix the image name with the Docker Hub username (for example, dockerhubusername/hellodockertools) if the image is pushed to the registry. Alternatively, change the image name to include the private registry URL (for example, privateregistry.domain.com/hellodockertools) depending on the configuration.
Code file modifications require compilation and a restart of Kestrel within the container. After making the change, use CTRL+F5 to perform the process and start the app within the container. The Docker container isn't rebuilt or stopped. Run the docker ps command in PMC. Notice the original container is still running as of 10 minutes ago:
So the natural next questions are, how can I see my other files? And how can my container write data that I can read later and maybe use in other containers? This is where bind mounts and volumes come in. Both of these use the -v flag to docker run to specify some files to share with the container.
The second option, a named volume, is a filesystem managed by Docker. You can create a named volume with a command like docker volume create new_vol, and then share it into the container using the -v flag again:
These volumes persist even after the container has been deleted, and can be shared with other containers. You can also browse their contents from the Docker Desktop UI, using the Volumes tab that we added recently (and that is now free for all users including Docker Personal).
Michael, is there any resource online to show how to do this? I have a windows 10 docker installation using the windows containers mode, and I want my sql server express db in the container to store its data in a host volume
To operate, Docker Toolbox installs a VirtualBox virtual machine named default, running the boot2docker Linux distribution. Because of this additional layer of virtualisation, additional steps are needed when sharing volumes between the host operating system and a Docker container. For example, a computer lab that I use for teaching runs Windows 7 with restricted student access. I have convinced our IT team to install Docker Toolbox, but my students still need some way of sharing a folder on their student drive (herein referred to as the H:\ drive) with the Docker container.
To achieve this, the folder (e.g. H:\work) needs to be shared with the VirtualBox virtual machine named default, before it can be mounted as a volume within a Docker container. There may be other approaches, but here are the steps for our particular set-up:
This may take some time, as it will need to download and extract the image. Once it's finished, you should be able to access the Jupyter notebook using 127.0.0.1:8888. I hope this helps you get up and running with Docker Toolbox and shared folders. Of course, the process is typically easier when using the non-legacy Docker solutions.
If you have shared your drives before, please check whether the credentials are still valid. If you have changed your Windows password since, you will also have to update the credentials in Docker for Windows.
Stick with alphanumeric passwords to avoid drive sharing problems. When asked to share your drives on Windows, you will be prompted for the username and password of an account with admin privileges on the machine. If you are warned about an incorrect username or password, this may be due to special characters in the password. For example, !, [ and ] are known to cause issues. Change your password to alphanumeric characters to resolve. See this issue about Docker volume mounting problems for details.
The VS Code Dev Containers extension can only automatically mount your source code into a container if your code is in a folder or drive shared with Docker. If you open a dev container from a non-shared location, the container will successfully start but the workspace will be empty.
There is known issue with Docker for Mac that can drive high CPU spikes. In particular, high CPU usage occurring when watching files and building. If you see high CPU usage for com.docker.hyperkit in Activity Monitor while very little is going on in your dev container, you are likely hitting this issue. Follow the Docker issue for updates and fixes.
The Develop inside a container on a remote Docker Machine or SSH host article covers how to setup VS Code when working with a remote Docker host. This is often as simple as setting the Docker extension docker.environment property in settings.json or the DOCKER_HOST environment variable to a ssh:// or tcp:// URI.
Just a reminder for people searching for a solution: Do you have a VPN connection up and running?I had the same issue, and search around on the internett for solution. Tried every solution found (including this one), but nothing worked. Firewall still blocking! Finally I realized my VPN Connection was up and running (blush!), and blocked the drive sharing in docker. After disconnecting VPN, the share just went fine. Then I could restart the VPN Connection, and startup my docker container (With mounted folder on shared disk).
On Linux, to build and run Lambda functions with a different instruction set architecture than your host machine, there are additional steps to configure Docker. For example, to run arm64 functions on an x86_64 machine, you can run the following command to configure the Docker daemon: docker run --rm --privileged multiarch/qemu-user-static --reset -p yes.
The container management system Docker is quite useful for running services or applications in a controlled, isolated environment. In a lot of situations it is also useful to have directories inside a docker container mapped to a local folder on the host system.Especially in a development environment, where this setup allows you to modify source files (e.g. for a web application) in the host-volume directly in your IDE, and have the running docker service find those updated files immediately without the need for a deployment.
The account used to authenticate with your Shared Drives needs to be the same as the one used to run docker commands. Otherwise, you will not be able to access the shared drive from your container. Also, for security reasons you will not be able to use an account that doesn't have a defined password.
The following commands run a docker container that creates, and then removes, a directory in each of the directories used by Appsody. The commands indicate the successful outcome of the validation if the shared drive access and the filesystem permissions are set correctly:
Error: Docker: A firewall is blocking file Sharing between Windows and the containers. See documentation for more infoShared drives require port 445 to be open between the host machine and the virtual machine that runs Linux containers. Docker detects if port 445 is closed and shows the following message when you try to add a shared drive:Description: This is the error I am getting when I actually try to share C:\ and D:\ of my PC in Docker.
Permission for shared drives are tied to the credentials you provide here. Ifyou run docker commands under a different username than the one configuredhere, your containers cannot access the mounted volumes.
Shared drives are only required for mounting volumes in Linux containers, not for Windows containers. For Linux containers, you need to share the drive where the Dockerfile and volume are located. If you get errors such as file not found or cannot start service you may need to enable shared drives. See Volume mounting requires shared drives for Linux containers.)
Shared drives require port 445 to be open between the host machine and thevirtual machine that runs Linux containers. Docker detects if port 445 is closedand shows the following message when you try to add a shared drive:
Note:(1) If the shared drive has already been deleted in Google Workspace, you can choose to also remove it from the shared drive list in CubeBackup. This will completely delete the shared drive so it will no longer appear in the CubeBackup web console.(2) To remove multiple Shared drives at the same time, you can create a batch file that includes the following command for each Shared drive to be removed:
Note:(1) This command requires special privileges and must be run by the cbuser account.(2) If the shared drive has already been deleted in Google Workspace, you can choose to also remove it from the shared drive list in CubeBackup. This will completely delete the shared drive so it will no longer appear in the CubeBackup web console.(3) To remove multiple Shared drives at the same time, you can create a bash script that includes the following command for each Shared drive to be removed:
If you manually mount the shared folder, then you need to use the relevant options on the mount command to set the folder with the right ownership (i.e. the gid, uid and umask options to mount). This is because the Host OS doesn't support the same permission system as Linux, so VirtualBox has no way of knowing who should own the files.
I just have had the same problem with my Win-Ubuntu shared folder, and the way I solved it was adding my user into the vboxsf group, editing the /etc/group file.Hope this works for you. Down here you can find a short scheme of how I edited the file 2ff7e9595c
