If not supplied, defaults to Docker Hub. |\n| * | SOURCE_IMAGE | Source Image. i.e. `alpine` or `rjchicago/docker-duper` |\n| | DESTINATION_REGISTRY | Destination Registry. i.e. `localhost:5000`. If not supplied, defaults to Docker Hub. |\n| | DESTINATION_IMAGE | Destination Image. If not supplied, defaults to $SOURCE_IMAGE |\n| | DESTINATION_USER | Destination Registry User. |\n| | DESTINATION_PASSWORD | Destination Registry Password. |\n| | TAG | Tag to copy. If not supplied, defaults to `latest`. |\n\n## Example\n\nThe following will copy `alpine:edge` from Alpine's official `Docker Hub` repo to `localhost:5000`:\n\n``` sh\ndocker run --rm \\\n -v /var/run/docker.sock:/var/run/docker.sock \\\n -e IMAGE=\"alpine\" \\\n -e TAG=edge \\\n -e DESTINATION_REGISTRY=\"localhost:5000\" \\\n rjchicago/docker-duper\n```\n\n> **NOTE**: update `localhost:5000` with your registry\n\nThe following will copy `alpine:edge` from Alpine's official `Docker Hub` repo to my personal `Docker Hub` repo:\n\n``` sh\nUSER=rjchicago\nIMAGE=alpine\nTAG=3.12\ndocker run --rm -it \\\n -v /var/run/docker.sock:/var/run/docker.sock \\\n -e SOURCE_IMAGE=\"$IMAGE\" \\\n -e DESTINATION_IMAGE=\"$USER/$IMAGE\" \\\n -e DESTINATION_USER=\"$USER\" \\\n -e TAG=\"$TAG\" \\\n rjchicago/docker-duper sh\n```\n\nThe following will copy `alpine:edge` from Alpine's official `Docker Hub` repo to a private `DTR` repo:\n\n``` sh\nDTR=dtr.cnvr.net\nIMAGE=alpine\nTAG=3.12\ndocker run --rm -it \\\n -v /var/run/docker.sock:/var/run/docker.sock \\\n -e SOURCE_IMAGE=\"$IMAGE\" \\\n -e DESTINATION_REGISTRY=\"$DTR\" \\\n -e DESTINATION_IMAGE=\"$(whoami)/$IMAGE\" \\\n -e DESTINATION_USER=\"$(whoami)\" \\\n -e TAG=\"$TAG\" \\\n rjchicago/docker-duper sh\n```\n\n## docker-duper demo\n\n### Note on Insecure Registries\n\nIn order to run the demo, you will need to update your Docker insecure registries:\nhttps://docs.docker.com/registry/insecure/\n\nFor this demo, add `localhost:5000`\n\n### Demo Up\n\nTo run the full demo, clone this repo and run the following script:\n\n``` sh\nsh demo\\demo-up.sh\n```\n\nThe demo will spin up a registry and copy in a couple of images.\n\nLastly, the demo should pop open a Web browser to http://localhost:8080\n\n### Demo Down\n\nTo complete and end the demo, run the following script:\n\n``` sh\nsh demo\\demo-down.sh\n```\n\n## single purpose containers\n\n### Docker Run\n\nYou can run single purpose containers to copy images as needed.\n\nAn official image of `docker-duper` is available on Docker Hub:\n\n* https://hub.docker.com/r/rjchicago/docker-duper\n\nFor this example, we'll run the local registry (see note on [insecure registries](#note-insecure-registries)):\n\n``` sh\ndocker-compose -f docker-registry.yml up -d\n```\n\nNext, we'll run a single purpose container to copy `docker-duper` to our registry:\n\n``` sh\ndocker run --rm \\\n -v /var/run/docker.sock:/var/run/docker.sock \\\n -e IMAGE=\"rjchicago/docker-duper\" \\\n -e DESTINATION_REGISTRY=\"localhost:5000\" \\\n rjchicago/docker-duper\n```\n\nPreview your registry at http://localhost:8080\n\nNow let's copy over the `alpine:latest` and `alpine:edge` images:\n\n``` sh\ndocker run --rm \\\n -v /var/run/docker.sock:/var/run/docker.sock \\\n -e IMAGE=\"alpine\" \\\n -e DESTINATION_REGISTRY=\"localhost:5000\" \\\n rjchicago/docker-duper\n```\n\n``` sh\ndocker run --rm \\\n -v /var/run/docker.sock:/var/run/docker.sock \\\n -e IMAGE=\"alpine\" \\\n -e TAG=edge \\\n -e DESTINATION_REGISTRY=\"localhost:5000\" \\\n rjchicago/docker-duper\n```\n\nWhen you're done, don't forget to compose down the demo registry:\n\n``` sh\ndocker-compose -f docker-registry.yml down\n```\n","has_starred","hub_user","immutable_tags_settings",{"_75":11,"_76":77},"enabled","rules",[78],".*","is_automated","permissions",{"_82":21,"_83":11,"_84":11},"read","write","admin","user","storage_size",120538137,"orgData","recentTags",[91],{"_92":44,"_93":94,"_95":96,"_97":98,"_99":100,"_50":118,"_119":94,"_120":33,"_121":56,"_57":122,"_123":124,"_125":109,"_126":118,"_127":65,"_128":21},"content_type","creator",876947,"full_size",66572573,"id",50560918,"images",[101],{"_102":103,"_104":105,"_106":107,"_108":109,"_110":111,"_112":113,"_114":107,"_115":-5,"_116":96,"_63":65,"_117":-5},"architecture","amd64","digest","sha256:11f670334c4ec42d476a7cea23d57830f702d65a9b08bf0e6523ff2948463505","features","","last_pulled","2026-10-05T15:39:48.913148639Z","last_pushed","2020-06-22T18:50:44Z","os","linux","os_features","os_version","size","variant","2020-06-22T18:50:44.319656Z","last_updater","last_updater_username","media_type","latest","repository",6872269,"tag_last_pulled","tag_last_pushed","tag_status","v2","sbxKitMetadata","isPotentialSpam","isHubSbxKitsEnabled","showSbxLogoOverride","sbxTrademarkText","displaySecurityMetadata","tagAttestations","tagsHaveAttestations",[],"selectedTag","attestationsUrl","routes/_layout.r.$namespace.$reponame.tags",{"_38":142,"_149":150,"_136":159,"_160":11},{"_40":143,"_42":144,"_45":46,"_47":48,"_49":11,"_50":51,"_52":53,"_54":145,"_57":35,"_32":33,"_58":59,"_60":44,"_61":62,"_63":62,"_64":65,"_66":-5,"_67":68,"_69":70,"_71":11,"_72":33,"_73":146,"_79":11,"_80":148,"_85":33,"_86":87},[],[44],[56],{"_75":11,"_76":147},[78],{"_82":21,"_83":11,"_84":11},"tags",{"_151":62,"_152":-5,"_153":-5,"_154":155},"count","next","previous","results",[156],{"_92":44,"_93":94,"_95":96,"_97":98,"_99":157,"_50":118,"_119":94,"_120":33,"_121":56,"_57":122,"_123":124,"_125":109,"_126":118,"_127":65,"_128":21},[158],{"_102":103,"_104":105,"_106":107,"_108":109,"_110":111,"_112":113,"_114":107,"_115":-5,"_116":96,"_63":65,"_117":-5},[],"canDeleteTags","actionData","errors"]
