You can update the container to install Supervisor and create a container with multiple services.

The Dockerfile below includes some extra software for debug and test.

Here are the changes:

  • Install SSH and enable password login
  • Install and configure Remote.It
  • Add a Supervisor configuration file

Use a text editor to replace your Dockerfile with the new file below:


            FROM ubuntu:22.04

RUN apt-get update && apt-get install -y curl iproute2 sudo openssh-server sudo vim apache2 supervisor procps uuid-runtime

# Configure SSH for password login
RUN mkdir -p /var/run/sshd
RUN sed -i '/PasswordAuthentication no/c\PasswordAuthentication yes' /etc/ssh/sshd_config
RUN sed 's@session\s*required\s* optional' -i /etc/pam.d/sshd

# Configure Remote.It
RUN mkdir -p /etc/remoteit
RUN touch /etc/remoteit/registration
RUN sh -c "$(curl -L"

# Configure Supervisor
COPY supervisord.conf /etc/supervisor/conf.d/supervisord.conf

# Setup default user
RUN useradd --create-home -s /bin/bash -m ubuntu && echo "ubuntu:ubuntu" | chpasswd && adduser ubuntu sudo
RUN echo '%sudo ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers

CMD ["/usr/bin/supervisord"]

You will also need a configuration file for Supervisor.

Use a text editor to create a file named supervisord.conf with the following contents:


logfile = /var/log/supervisord.log

command=/usr/sbin/sshd -D


command=/usr/sbin/apache2ctl -DFOREGROUND

Build the container using:


            docker build -t supervisord-dev  .

Before running the container, you need a registration code from Remote.It.

Log in to your account at .

From the dashboard click the + icon and select the Linux icon to add a new device.

Copy the generated registration code by clicking the bar code symbol under COPY as shown below:

Image Alt Text:Registration code

With this code you can launch the container. Substitute your registration code instead of the one shown below:


            docker run -d -e R3_REGISTRATION_CODE=416ED829-D9D8-532C-B1FE-13548929B2A1 -p 80:80 supervisord-dev

Once the container starts on your local machine, you can open your browser to https://localhost and see the Apache welcome screen.

You will also see the device in your Remote.It dashboard.

In the dashboard, start the SSH connection by clicking the CONNECT bar as shown below:

Image Alt Text:Connect

Once connected, get the values for the PUBLIC ENDPOINT:

Image Alt Text:Public endpoint

You can now SSH directly into the container. The username for the container is ubuntu and the password is also ubuntu. If desired, you can change this in the Dockerfile.

Change to your endpoint values in the command below to SSH:


            ssh ssh://

You are now inside the container as the ubuntu user.

Notice that the SSH port was not shared by the container.
