# Postgresql
|
|
|
|
A database for all those awesome services you'll be running.
|
|
|
|
## Install / Update / Run Script
|
|
|
|
Setup a generic script that'll auto update, build a container and launch it. You should only run this script at first launch and/or when you're looking for updates.
|
|
|
|
If you are running your operating system from a Micro SD Card, You may wish to store your data directory on a [USB drive](../hardware/usb-flash-drive.md) to reduce the number of writes to the SD card. If you do so, don't forget to change the volume mount path when starting the docker container.
|
|
|
|
``` bash
|
|
|
|
# Create directory for postgres to store data.
|
|
# Alternatively, create a directory on a USB drive
|
|
mkdir -p /var/postgres/data
|
|
|
|
cat > /scratch/docker/postgres.sh << EOF
|
|
#!/bin/bash
|
|
|
|
VERSION=""
|
|
|
|
ARCH=\`arch\`
|
|
|
|
# Cleanup arch/container image here.
|
|
if [ \$ARCH == "aarch64" ]
|
|
then
|
|
echo "64bit arm"
|
|
VERSION="arm64v8/postgres:latest"
|
|
else
|
|
echo "32bit arm"
|
|
VERSION="arm32v7/postgres:latest"

docker pull \$VERSION

|
|
# Cleanup existing container.
|
|
docker stop postgres
|
|
docker rm postgres
|
|
|
|
# Re-run/create container with latest image.
