如何使用主机当前用户运行 docker
这里提供两种方法：
Method 1: Using –user Flag
Get Current User’s UID and GID: You need to retrieve your current user’s UID (User ID) and GID (Group ID). You can do this with the following commands:
1
2
export UID=$(id -u)
export GID=$(id -g)
Run Docker Container: Use the –user flag to specify the UID and GID when running your Docker container. Here’s an example command:
1
docker run -it --rm --user $UID:$GID -v "$(pwd):/home/user" <IMAGE_NAME>
Replace
Method 2: Using a Custom Dockerfile
If you frequently need containers running as a specific user, consider creating a custom Docker image: Create a Dockerfile: Include the following lines in your Dockerfile to accept UID and GID as build arguments:
1
2
3
4
5
6
7
8
9
10
11
FROM ubuntu
ARG UID
ARG GID
RUN groupadd --gid $GID nonroot && \
useradd --uid $UID --gid $GID --create-home nonroot && \
echo 'nonroot ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers
USER nonroot
WORKDIR /home/nonroot
Build the Image: Build the image while passing your host’s UID and GID:
1
docker build --build-arg UID=$(id -u) --build-arg GID=$(id -g) -t your-image-name .
Run Your Container: Run the container using your custom image:
1
docker run -it --rm your-image-name
This method creates a user inside the container that matches your host’s user, ensuring consistent permissions across both environments.
