# Dockerfile Snippets
These snippets are tested on `debian:bookworm` based images.
They should help save time when creating Dockerfiles, especially for [VS Code Dev Containers](https://code.visualstudio.com/docs/devcontainers/containers).

## Install PostgreSQL
```Dockerfile
######################################
### 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:
```bash
# 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.log
```
These commands could also be added to the Dockerfile if you prefer.

RUN if getent group docker > /dev/null 2>&1; then \
echo "Docker group exists"; \
else \
groupadd docker; \
fi \
&& usermod -aG docker root
###############################################
### 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:
```json
"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:
```yaml
volumes:
- /var/run/docker.sock:/var/run/docker-host.sock
```
