For the last 3 years this blog was written using [Jekyll](https://jekyllrb.com/docs/installation/) which has a series of requirements such as Ruby that I don't want to keep installing or maintaining on my PC. So I created this Developer Container for those who want to use Jekyll from an isolated container.

Let's check the container definition:

## 1. devcontainer.json file

* * *

This file configures the remote container with the specified extensions

```
{
"name": "Jekyll",
"dockerFile": "Dockerfile",
// Use 'settings' to set *default* container specific settings.json values on container create.
// You can edit these settings after create using File > Preferences > Settings > Remote.
"settings": {
"terminal.integrated.shell.linux": "/bin/bash"
},
// Use 'appPort' to create a container with published ports. If the port isn't working, be sure
// your server accepts connections from all interfaces (0.0.0.0 or '*'), not just localhost.
// "appPort": ["3000:3000"],
// Uncomment the next line to run commands after the container is created.
// "postCreateCommand": "cd ${input:projectName} && bundle install",
// Uncomment the next line to use a non-root user. On Linux, this will prevent
// new files getting created as root, but you may need to update the USER_UID
// and USER_GID in .devcontainer/Dockerfile to match your user if not 1000.
// "runArgs": ["-u", "vscode"],
// Add the IDs of extensions you want installed when the container is created in the array below.
"extensions": []
}

```

## 2. Dockerfile

* * *

This is the Dockerfile with all the tooling for the Jekyll environment.

```
FROM debian:latest

# Avoid warnings by switching to noninteractive
ENV DEBIAN_FRONTEND=noninteractive
# This Dockerfile adds a non-root 'vscode' user with sudo access. However, for Linux,
# this user's GID/UID must match your local user UID/GID to avoid permission issues
# with bind mounts. Update USER_UID / USER_GID if yours is not 1000. See
# https://aka.ms/vscode-remote/containers/non-root-user for details.
ARG USERNAME=vscode
ARG USER_UID=1000
ARG USER_GID=$USER_UID

# Configure apt and install packages
RUN apt-get update \
 && apt-get -y install --no-install-recommends apt-utils dialog 2>&1 \
 #
 # Install vim, git, process tools, lsb-release
 && apt-get install -y \
 git \
 #
 # Install ruby
 && apt-get install -y \

 #
 # Install jekyll

 #

 && groupadd --gid $USER_GID $USERNAME \
 && useradd -s /bin/bash --uid $USER_UID --gid $USER_GID -m $USERNAME \
 # [Optional] Add sudo support for the non-root user
 && apt-get install -y sudo \
 && echo $USERNAME ALL=\(root\) NOPASSWD:ALL > /etc/sudoers.d/$USERNAME\
 && chmod 0440 /etc/sudoers.d/$USERNAME \
 #
 # Clean up
 && apt-get autoremove -y \
 && apt-get clean -y \
 && rm -rf /var/lib/apt/lists/*

# Switch back to dialog for any ad-hoc use of apt-get
ENV DEBIAN_FRONTEND=dialog
