DB Container Backup Script Template

This backup script can be used to automatically backup databases in docker containers.

It currently supports mariadb, mysql and bitwardenrs containers.

DAYS=2 BACKUPDIR=/home/barkingb/backups

backup all mysql/mariadb containers

CONTAINER=$(docker ps --format '{{.Names}}:{{.Image}}' | grep 'mysql|mariadb' | cut -d":" -f1)

echo $CONTAINER

if [ ! -d $BACKUPDIR ]; then mkdir -p $BACKUPDIR fi

for i in $CONTAINER; do MYSQL_DATABASE=$(docker exec $i env | grep MYSQL_DATABASE |cut -d"=" -f2-) MYSQL_PWD=$(docker exec $i env | grep MYSQL_ROOT_PASSWORD |cut -d"=" -f2-)

docker exec -e MYSQL_DATABASE=$MYSQL_DATABASE -e MYSQL_PWD=$MYSQL_PWD \
    $i /usr/bin/mysqldump -u root $MYSQL_DATABASE \
    | gzip > $BACKUPDIR/$i-$MYSQL_DATABASE-$(date +"%Y%m%d%H%M").sql.gz

OLD_BACKUPS=$(ls -1 $BACKUPDIR/$i*.gz |wc -l)
if [ $OLD_BACKUPS -gt $DAYS ]; then
    find $BACKUPDIR -name "$i*.gz" -daystart -mtime +$DAYS -delete

The problem is likely your Linux distro doesn't allow executable scripts in the /tmp directory. I think "hardened" Linux flavors have this restriction.

See this issue: https://github.com/jhuckaby/Cronicle/issues/133

[coffseducation]

Ok, thanks.

I added "TMPDIR" to environment variables with /home/barkingb/tmp but got Error: ENOENT: no such file or directory, open '/home/barkingb/tmp/cronicle-script-temp-jlreb3sjr04.sh'

I suppose I need to un-harden /tmp

Cheers.

[jhuckaby]

Does /home/barkingb/tmp exist? You'll have to pre-create it, and chmod it to 777, like /tmp is.

But yeah, unhardening /tmp would probably work best.

Good luck!

[coffseducation]

I had created the tmp but had not chmod 777 it. It still does not work. Error: ENOENT: no such file or directory, open '/home/barkingb/tmp/cronicle-script-temp-jlree04cu03.sh'

I cannot find any info on how to unharden /tmp so I think I will look into doing a manual entry in crontab.

Thanks so much for your help!

[jhuckaby]

Oh, how weird. I don't know anything about hardened Linux, so forgive my lack of knowledge here, but I wonder if it has something to do with traversing into your home directory. Maybe try something like /opt/cronicle/tmp ?

[jhuckaby]

Wow, okay, I am at a loss. I have no idea how to solve this one. I'll re-open this issue, so others can see it.
