如何在 Spyder 中运行 Docker 容器

Question

I have docker image/container with virtual environment and currently I'm able to run it in VS Code using Remote Development extension. Is it possible to do something similar in Spyder?

EDIT: That's what I've done so far:

My dockerfile:

FROM ubuntu:latest
RUN apt update && apt install  openssh-server sudo -y

# Create a user “sshuser” and group “sshgroup”
RUN groupadd sshgroup && useradd -ms /bin/bash -g sshgroup sshuser
# Create sshuser directory in home
RUN mkdir -p /home/sshuser/.ssh
# Copy the ssh public key in the authorized_keys file. The idkey.pub below is a public key file you get from ssh-keygen. They are under ~/.ssh directory by default.
COPY key.pub /home/sshuser/.ssh/authorized_keys
# change ownership of the key file. 
RUN chown sshuser:sshgroup /home/sshuser/.ssh/authorized_keys && chmod 600 /home/sshuser/.ssh/authorized_keys
# Start SSH service
RUN service ssh start
# Expose docker port 22
EXPOSE 22
CMD ["/usr/sbin/sshd","-D"]

USER root
RUN apt update
RUN apt-get install python3-pip -y
RUN pip install jupyter
RUN pip install spyder-kernels

Then in powershell I typed:

docker run -d -p 2022:22 sshubuntu
ssh -i key sshuser@localhost -p 2022 # (here I typed my password and successfully logged into container)
jupyter --runtime-dir # /home/sshuser/.local/share/jupyter/runtime
python3 -m spyder_kernels.console

Now using another instance of powershell I copied json to local machine:

docker cp 21ff6e147a2d:/home/sshuser/.local/share/jupyter/runtime/kernel-24.json .

The file is:

{
  "shell_port": 46227,
  "iopub_port": 34519,
  "stdin_port": 43075,
  "control_port": 38781,
  "hb_port": 44761,
  "ip": "127.0.0.1",
  "key": "1c925c4a-983896e82c953e4fccb7ce90",
  "transport": "tcp",
  "signature_scheme": "hmac-sha256",
  "kernel_name": ""
}

Finally I opened Spyder and typed the following:

Spyder

The results is that "Connecting to kernel..." appears and nothing happenes. What am I doing wrong that it doesnt work?

( Spyder maintainer here ) The best you can do at the moment is starting a kernel in the container and connect to it from Spyder through SSH. The instructions for that are described here .
