How to share files with Docker Toolbox

Introduction

If you mount any folder on your local PC in the container launched by Docker You can freely put files in the closed NW in docker! I think, and summarize the results of my research

Why are you posting such an article now?

If you search for "Docker windows file sharing" on google, you'll be killed instantly. ・ When I looked at the content of the article, it was actually for Docker for Windows (* PCs that cannot run Hyper-V clients are not helpful because they use the Docker environment with Docker Toolbox). -Although there was a virtualbox setting (described later), the format of the command method on docker after that was ambiguous, so I did not understand well after all. I didn't like the environment I was in, so I had a hard time, so Leave it in the article so that you can start over even if the PC flies.

Procedure (overview)

I don't know from just the outline, but the point is that there are 3 steps in total, so I'll leave it as a memo.

1. 1. Set up shared folders in Virtualbox
2. Create a shared folder for the container with Docker Machine, and 1. Mount the shared folder of
3. 3. Mount the container in the shared folder for the container and any directory of the container and start it.

Procedure (details)

1. 1. Set up shared folders in Virtualbox

1. 1. Start Oracle VM VirtualBox
2. default → right click → settings
3. 3. Click on shared folder
4. Click the Add New Shared Folder icon on the right side of the window that pops up
5. Enter the following contents and click "OK" Folder path: Enter the folder path of the local PC you want to use as a shared folder Example) C: \ Users \ watya \ work \ docker Folder name: Folder name when docker-machine recognizes it The point is to replace it with C: \ → / C /, \ → / Example) / C / Users / watya / work / docker

2. Create a shared folder for the container with Docker Machine, and 1. Mount the shared folder of

Start Docker Quickstart Terminal and execute the command. Use the following command to add 1. Mount the shared folder set in. With this, file sharing is connected by the connection of local PC → VirtualBox → Docker machine. The directory name created on the Docker Machine side is e, but anything is fine as long as it is not covered. Personally, I like it because it looks like a drive number and it is easy to understand that it is a shared folder.

DockerToolbox

$ docker-machine ssh default 'sudo mkdir -p /e'
$ docker-machine ssh default 'sudo mount -t vboxsf -o uid=0,gid=0 /C/Users/watya/work/docker /e'

3. 3. Mount the container in the shared folder for the container and any directory of the container and start it.

Execute the command from Docker Toolbox. With the following command, 2. / E created in is mounted in / home of nginx container.

DockerToolbox

$ docker run -d -v /e:/home --name nginx nginx

If you log in for confirmation and check the contents of / home, you can confirm that it is mounted safely

Note: Set to mount automatically when Docker Machine starts
