These snippets are tested on debian:bookworm based images.
They should help save time when creating Dockerfiles, especially for VS Code Dev Containers.
If you have any suggestions or improvements, please feel free to open an issue or pull request. Useful snippets are always welcome.

### START # Install PostgreSQL #######
######################################
# Set PostgreSQL version
ARG POSTGRESQL_MAJOR=16
# Install Dependencies
RUN apt install -y wget
# Create the file repository configuration:
RUN sh -c 'echo "deb https://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
# Import the repository signing key:
RUN wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -
# Update the package lists:
RUN apt update
# Install PostgreSQL.
RUN apt -y install postgresql-${POSTGRESQL_MAJOR}
# Set locale
ENV LC_ALL=C
# Set postgres password
RUN service postgresql start && \
su -c "psql -c \"ALTER USER postgres PASSWORD 'postgres';\"" - postgres && \
service postgresql stop
# Allow remote connections
RUN echo "host all all 0.0.0.0/0 md5" >> /etc/postgresql/16/main/pg_hba.conf && \
echo "listen_addresses='*'" >> /etc/postgresql/16/main/postgresql.conf && \
sed -i 's/local all postgres peer/local all postgres md5/' /etc/postgresql/16/main/pg_hba.conf
To start the server, these commands can be used with a shell script entrypoint:
# Adjust ownership
chown -R postgres:postgres /var/lib/postgresql/16/main
# Start the postgres server
service postgresql start
# Tail the PostgreSQL log file to keep the container running
tail -f /var/log/postgresql/postgresql-16-main.logThese commands could also be added to the Dockerfile if you prefer.

### END # Install Docker with Host Socket #####
###############################################If you are using this for a VS Code devcontainer, you should add the following to your .devcontainer/devcontainer.json file to allow the container to access the host socket:
"mounts": [
"source=/var/run/docker.sock,target=/var/run/docker-host.sock,type=bind"
]If you are using the docker-compose.yml file to allow the container to access the host socket, you can instead add the following to your docker-compose.yml file under the volumes section if the container:
volumes:
- /var/run/docker.sock:/var/run/docker-host.sock
