install registry

nel file docker-compose.yml che può essere usato in portainer vanno mofificati alcuni parametri

- porta del registry e della sua UI (utilizzati qui 5557 e 5558)
- NGINX_PROXY_PASS_URL=http://192.168.1.4:5557
- REGISTRY_HTTP_HEADERS_Access-Control-Allow-Origin: '[http://images-ui.patachina.casacam.net]'

e i volumi

- /home/nvme/dockerdata/registry:/var/lib/registry
- /home/nvme/dockerdata/registry/config:/etc/docker/registry

nel volume /home/nvme/dockerdata/registry/config copiare il file 'config.yml'

impostare Nginx per puntare a server registry

come si usa

avere una immagine caricata e fare il pull per esempio di ubuntu con

sudo docker pull ubuntu

fare il tag sul server locale

sudo docker tag ubuntu images.patachina.casacam.net/ubuntu

fare il push sul server locale

sudo docker tag ubuntu images.patachina.casacam.net/ubuntu

ora si può scaricare l'immagine unubtu dal server locale anche quando si ha cancellato quella locale con

sudo docker pull images.patachina.casacam.net/ubuntu

se non si mette la versione lui usa l'ultima in questo esempio è

ubuntu:latest

inserire la versione se si vuole utilizzare solo quella

delete-docker-registry-image

Install

curl https://raw.githubusercontent.com/burnettk/delete-docker-registry-image/master/delete_docker_registry_image.py | sudo tee /usr/local/bin/delete_docker_registry_image >/dev/null
sudo chmod a+x /usr/local/bin/delete_docker_registry_image

Run

Set up your data directory via an environment variable:

export REGISTRY_DATA_DIR=/opt/registry_data/docker/registry/v2

You can also just edit the script where this variable is set to make it work for your setup.

Almost delete a repo:

delete_docker_registry_image --image testrepo/awesomeimage --dry-run

Actually delete a repo (remember to shut down your registry first):

delete_docker_registry_image --image testrepo/awesomeimage

Delete one tag from a repo:

delete_docker_registry_image --image testrepo/awesomeimage:supertag

clean_old_versions.py

This complimentary script is made to remove tags in repository based on regexp pattern.

Usage:

./clean_old_versions.py --image reg_exp_of_repository_to_find --include reg_exp_of_tag_to_find -l history_to_maintain --registry-url location_of_docker_registry -o tag_ordering -b only_tags_before_date -a only_tags_after_date

Example: Search for all images whose name start with 'repo/sitor' and delete all tags whose name start with '0.1.' keeping the last 2 tags and of the remaining tags deletes only those having an image creation time between January 1, 2016 12 a.m. and June 25, 2016 12 p.m. (both datetimes are exclusive).

./clean_old_versions.py --image '^repo/sitor*' --include '^0.1.*' -l 2 -b 2016-06-25T12:00:00 -a 2016-01-01T00:00:00 --registry-url http://localhost:5000

Add --dry-run as argument for a test run without actual removal of tags.
