Edit Docker Container in VSCode multi-stage SSH Vagrant

Create sshconfig

Create a config file in C: \ Users \ username \ .ssh and write the following

Host default
  HostName 127.0.0.1
  User vagrant
  Port 2222
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no
  IdentityFile D:/vagrant/centos7/.vagrant/machines/default/virtualbox/private_key
  IdentitiesOnly yes
  LogLevel FATAL

Execute the following with powershell

$ scp .vagrant/machines/default/virtualbox/private_key default:/home/vagrant/.ssh/

After logging in to vagrant, execute the following

$ vagrant ssh
# private_Change the execute permission of key
$ chmod 600 ~/.ssh/private_key

Transfer of private key

#Note`vagrant up`Run in the directory
> scp .vagrant/machines/default/virtualbox/private_key vagrant-os:/home/vagrant/.ssh/

#SSH connection to Guest OS
> vagrant ssh

# private_Change the execution authority of key (in Guest OS)
$ chmod 600 ~/.ssh/private_key

Launch Docker Container

FROM ruby:2.5.1

#Update repository and install dependent modules
RUN apt-get update -qq && \
    apt-get install -y build-essential \
                       nodejs

#Create a working directory with the name webapp directly under the root (application directory in the container)
RUN mkdir /webapp
WORKDIR /webapp

#Host Gemfile and Gemfile.Copy lock to container
ADD Gemfile /webapp/Gemfile
ADD Gemfile.lock /webapp/Gemfile.lock

#Run bundle install
RUN bundle install

#Copy everything in the host's application directory to a container
ADD . /webapp

# puma.Create a directory to place sock
RUN mkdir -p tmp/sockets


#From here to the end is the openssh setting
RUN apt-get update && apt-get install -y openssh-server
RUN mkdir /var/run/sshd

# /etc/ssh/sshd_Rewrite config settings
RUN sed -i 's/PermitRootLogin without-password/PermitRootLogin yes/' /etc/ssh/sshd_config
RUN sed -i 's/#PasswordAuthentication yes/PasswordAuthentication no/' /etc/ssh/sshd_config

# SSH login fix. Otherwise user is kicked off after login
RUN sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd

ENV NOTVISIBLE "in users profile"
RUN echo "export VISIBLE=now" >> /etc/profile

#Copy public key
COPY authorized_keys /root/authorized_keys

EXPOSE 22

# Activate authorized_keys & Boot sshd
CMD mkdir ~/.ssh && \
    mv ~/authorized_keys ~/.ssh/authorized_keys && \
    chmod 0600 ~/.ssh/authorized_keys &&  \
    #Finally start ssh
    /usr/sbin/sshd -D

#Copy public key
$ cp ~/.ssh/authorized_keys .

# build
$ docker build ./ -t example

#Launch Docker Container
# Port:10000 Port:Transfer to 22
$ docker run -d -p 10000:22 example

#SSH connection to Docker Container
$ ssh -o 'StrictHostKeyChecking no' [email protected] -p 10000 -i ~/.ssh/private_key

Check with powershell

$ ssh -o 'StrictHostKeyChecking no' docker-os
