You need to ask for an account on the c4science registry, see Account request.

Upload an image to Shifter from dockerhub using the registry.c4science.ch (preferred)

1. Get a docker image from dockerhub for instance

   Code Block
   theme Midnight
   $ docker pull alpine:latest $ docker images

   
   

2. Set up your machine

   Login on the registry from your local Docker installation (you need an account, see Account request)

   Code Block
   theme Midnight
   $ docker login registry.c4science.ch Username (username): username Password: Login Succeeded

   
   

3. Upload a Docker image to the registry

   • On the web interface, create a Project on the registry (private or public)

   • Tag the image you want to upload on your local machine and push it to the registry
     NOTE: Do not use the `-` character in the tag name, only letters, numbers and underscore

     Code Block
     theme Midnight
     $ docker tag alpine:latest registry.c4science.ch/yourproject/alpine:latest $ docker push registry.c4science.ch/yourproject/alpine:latest

     
     

4. Pull an image on Shifter and specify a user or group ACL
   
   

   • From each cluster frontend (i.e.: fidis.epfl.ch), login to the registry, pull the image and check it's was pulled with success.

     Code Block
     theme Midnight
     $ shifterimg login default username: <username> default password: $ shifterimg pull yourproject/alpine:latest $ shifterimg images tcm docker READY 9797e5e798 2018-03-15T16:00:59 yourproject/alpine:latest

     
     

   • You can specify one or multiple (separated by a comma) LDAP username and/or group so the image is only available to those people

     Code Block
     theme Midnight
     $ id $ shifterimg --group scitas-ge --user aubort,user2 pull yourproject/alpin

     
     

   • To update the user/group ACL you can re-run the pull command
   • The images are unique for each cluster (deneb, fidis, helvetios, izar)

   • To view the full info about the images (warning: JSON):

     Code Block
     theme Midnight collapse true
     $ shifterimg -v images Message: { "list": [ { "ENTRY": null, "ENV": [ "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" ], "WORKDIR": "MISSING", "groupACL": [], "id": "9797e5e798a034d53525968de25bd25c913e7bb17c6d068ebc778cb33e3ff6e5", "itype": "docker", "last_pull": 1536842228.15727, "status": "READY", "status_message": "", "system": "fdata2-int.fidis", "tag": [ "scitas/alpine:latest" ], "userACL": [] }, [...]
