clone-volume

Anonymous (anonymous@undisclosed.example.com) — 2022-06-11T12:35:45+00:00

Cloning a Volume Angelehnt an [|Andread Laub] (in German). The current docker volume-command has no rename option. This article shows how you can circumvent this restriction to rename a volume anyway. More correctly it copies the contents from one volume to new, correctly named volume and then deletes the old.

compose_update_container

Updating a single Container from Docker compose docker-compose up -d --no-deps --build

copy_files

Docker Copy files Container Good Examples Official Documentation The first example copies a file from the /tmp directory on the host machine into the Grafana install directory in the grafana container: docker cp /tmp/config.ini grafana:/usr/share/grafana/conf/ To copy files from the grafana container to the /tmp directory on the host machine, we just switch the order of the parameters:

cron

Docker Cron Passiert hin und wieder mal, dass man Docker braucht, der was mit cron macht. so gehts: FROM debian RUN apt update && apt install cron COPY ./crontab /etc/cron.d/tab.cron RUN crontab /etc/cron.d/tab.cron # test * * * * * echo "[~] dies ist ein test" > /proc/1/fd/1 2>/proc/1/fd/2

entrypoint_cmd

Anonymous (anonymous@undisclosed.example.com) — 2022-03-02T09:49:27+00:00

Docker Entrypoint vs CMD In the Dockerfile, the ENTRYPOINT command defines the executable, while CMD sets the default parameter.

ipv6

Anonymous (anonymous@undisclosed.example.com) — 2021-09-24T17:10:16+00:00

Docker IPv6 PD but more is needed, for prefix delegation: networking interfaces cannot automatically delegate the received prefix automatically.

Running multiple Services in one Docker container It doesnt look that simple tbh :(

networking_ipvlan

Anonymous (anonymous@undisclosed.example.com) — 2021-09-24T17:10:16+00:00

Docker Networks: IPVlan IPVlan Networks are like Virtual Switches on Hyper-V. It allows the containers direct access to the network without NAT or other crap. It also works with IPv6 Docker Docs Setup docker network create -d ipvlan \ -o eth0 \ --gateway=192.168.21.1 \ --subnet=192.168.21.0/24 \ externet

Move Volume between hosts Volume Data ist unter /var/lib/docker/volumes zuerst die volumes tarren. Das ist nötig, damit permissions bestehen bleiben. Alles muss als root ausgeführt werden. tar -cvf /mnt/fs17/docker.tar ./web_elasticsearch-data/ ./web_grafana/ ./web_zammad-data/
