Trying to sandbox Claude into Apple container and run but encounter error. Any suggestions?

[champlain007]

% docker sandbox run claude

docker image is docker/sandbox-templates:claude-code on my machine

% docker save -o ClaudeSandbox.tar docker/sandbox-templates:claude-code

saves docker image as ClaudeSandbox.tar OCI image in my Projects folder

% container system start
% container image load -i ClaudeSandbox.tar

seems like it loads correctly however I get an error once I try to run

% container run docker/sandbox-templates:claude-code
Error: Input must be provided either through stdin or as a prompt argument when using --print

Any suggestions to get the container running (as I am not using --print therefore not thinking of passing it anything)?

Following your steps, I noticed I would get the same errors. Feel free to use my script, if you would like.

Instructions:

1. Copy and paste the code below into a file.
2. Save the file and name it whatever you want, e.g., start.sh
3. In your terminal app, navigate to the directory containing your file.
4. Run chmod +x start.sh (or whatever you named the file)
5. Execute the file via ./start.sh
6. If no errors occurred, then you should be placed in the default working directory of the container, i.e., ~/workspace.
7. Run Claude-Code via the command claude
8. If container is powered off or deleted, then just run ./start.sh to jump back in.

(I chose the name of my container to be 'claude' for brevity. Feel free to name the container whatever you want.)

#!/bin/zsh

# Ensure container system is running (no-op if already started)
container system start 2>/dev/null || true

# Check if container already exists
EXISTS=$(container ls -a 2>/dev/null | grep -w claude || true)

if [ -n "$EXISTS" ]; then 
	container start claude 2>/dev/null || true
	exec container exec -it claude /bin/bash
fi

echo "Pulling base image..."
container image pull docker/sandbox-templates:claude-code

# See more at https://github.com/apple/container/tree/main/docs
# Choose whatever DNS Gateway you prefer. 
# My container cannot access Internet without changing default DNS (bug?). 
echo "Creating container..."
container create -it \
    --name claude \
    --cpus 2 \
    --memory 2g \
    --dns 8.8.8.8 \
    docker/sandbox-templates:claude-code

# Start the container with keep stdin open and active TTY process options. 
container start claude && container exec -it claude /bin/bash
