Harbor'da Backup ve Restore

Bu yazıda Harbor da backup ve restore işlemlerinin nasıl yapıldığını anlatacağım.
Öncelikle backup için bir harbor-backup.sh hazırlanır.
harbor-backup.sh :

create_dir(){
    rm -rf harbor
    mkdir -p harbor/db
    mkdir -p harbor/secret
    chmod 777 harbor
    chmod 777 harbor/db
    chmod 777 harbor/secret
}

launch_db() {
    if [ -n "$($DOCKER_CMD ps -q)" ]; then
        echo "There is running container, please stop and remove it before backup"
        exit 1
    fi
    $DOCKER_CMD run -d --name harbor-db -v ${PWD}/harbor:/backup/harbor -v ${harbor_db_path}:/var/lib/postgresql/data ${harbor_db_image} "postgres"
}

clean_db() {
    $DOCKER_CMD stop harbor-db
    $DOCKER_CMD rm harbor-db
}

wait_for_db_ready() {
    set +e
    TIMEOUT=12
    while [ $TIMEOUT -gt 0 ]; do
        $DOCKER_CMD exec harbor-db pg_isready | grep "accepting connections"
        if [ $? -eq 0 ]; then
                break
        fi
        TIMEOUT=$((TIMEOUT - 1))
        sleep 5
    done
    if [ $TIMEOUT -eq 0 ]; then
        echo "Harbor DB cannot reach within one minute."
        clean_db
        exit 1
    fi
    set -e
}

dump_database() {
    $DOCKER_CMD exec harbor-db sh -c 'pg_dump -U postgres registry > /backup/harbor/db/registry.back'

    $DOCKER_CMD exec harbor-db sh -c 'pg_dump -U postgres notarysigner > /backup/harbor/db/notarysigner.back'
    $DOCKER_CMD exec harbor-db sh -c 'pg_dump -U postgres notaryserver > /backup/harbor/db/notaryserver.back'
}

backup_registry() {
    cp -rf /data/registry  harbor/
}

    if [ -d /data/secret/ ]; then
        cp -r /data/secret/* harbor/secret/
    fi
    # exclude the server.crt and server.key because they should be signed with new ca
    if [ -d harbor/secret/cert/  ]; then
        rm -rf harbor/secret/cert/
    fi
}

create_tarball() {
    timestamp=$(date +"%Y-%m-%d-%H-%M-%S")
    backup_filename=harbor-$timestamp.tgz
    tar zcvf $backup_filename harbor
    rm -rf harbor
}

note() { printf "\nNote:%s\n" "$@"

sudo nano harbor-backup.sh

Harbor için yedek alındıktan sonra restore işlemine başlanır.
harbor-restore

docker stop harbor-db
docker rm harbor-db (çalışan konteynarlar kaldırılır.)

chmod +x ./harbor-restore.sh
