It retains Dockerfile commands such as PORT,\nENV, etc.. so that squashed images work the same as they were originally built. In addition, deleted\nfiles in later layers are actually purged from the image when squashed.\n\nIt's designed to support a workflow where you would squash the image just before pushing it\nto a registry. Before squashing the image, you would remove any build time dependencies, extra\nfiles (apt caches, logs, private keys, etc..) that you would not want to deploy. The defaults also\npreseve your base image so that it's contents are not repeatedly transferred when pushing and pulling\nimages.\n\nTypical workflow is:\n\n* Build image from Dockerfile (or other)\n* Run clean up commands in container (apt-get purge, rm /path, etc..)\n* Commit container\n* Squash the image\n* Push squashed image to registry\n\nSee [Squashing Docker Images](http://jasonwilder.com/blog/2014/08/19/squashing-docker-images/)\n\n## Sample Output\n\n```\n$ docker save 49b5a7a88d5 | sudo docker-squash -t squash -verbose | docker load\nLoading export from STDIN using /tmp/docker-squash683466637 for tempdir\nLoaded image w/ 15 layers\nExtracting layers...\n - /tmp/docker-squash683466637/49b5a7a88d5353fe77204ad5591a3ef100fc2807a9d6dce979fd1b17a73a68d6/layer.tar\n - /tmp/docker-squash683466637/651626d6e364ccc22ac990ba95cd0aab9256c56055087cc9a5a1790cea5250b9/layer.tar\n - /tmp/docker-squash683466637/c50f2b65cab3b74f9bdb6f616b36f132b9a182ed883d03f11173e32fa39ab599/layer.tar\n - /tmp/docker-squash683466637/d92c3c92fa73ba974eb409217bb86d8317b0727f42b73ef5a05153b729aaf96b/layer.tar\n - /tmp/docker-squash683466637/511136ea3c5a64f264b78b5433614aec563103b4d4702f3ba7d4d2698e22c158/layer.tar\n - /tmp/docker-squash683466637/1c9383292a8ff4c4196ff4ffa36e5ff24cb217606a8d1f471f4ad27c4690e290/layer.tar\n - /tmp/docker-squash683466637/589338fba5eb5cc32a25a036975a5e0938f12eff0dc70b661363c13ef1a192a5/layer.tar\n - /tmp/docker-squash683466637/63e174c2ca3d53e2b7639a440940e16e15c1970e6ad16f740ffdcc60e59e0324/layer.tar\n - /tmp/docker-squash683466637/9942dd43ff211ba917d03637006a83934e847c003bef900e4808be8021dca7bd/layer.tar\n - /tmp/docker-squash683466637/0ea0d582fd9027540c1f50c7f0149b237ed483d2b95ac8d107f9db5a912b4240/layer.tar\n - /tmp/docker-squash683466637/8dfc0bb00563dab615dfcc28ab3e338089f5b1d71d82d731c18cbe9f7667435f/layer.tar\n - /tmp/docker-squash683466637/c4ff7513909dedf4ddf3a450aea68cd817c42e698ebccf54755973576525c416/layer.tar\n - /tmp/docker-squash683466637/cc58e55aa5a53b572f3b9009eb07e50989553b95a1545a27dcec830939892dba/layer.tar\n - /tmp/docker-squash683466637/e4eea4411c0065f8b0c7cf6be31dd58daa5ac04d8c64d54537cbfce2eb8e3413/layer.tar\n - /tmp/docker-squash683466637/fc294d2b22cb53cb2440ff6fece18813ee7363f5198f5e20346abfcf7cce54fe/layer.tar\nInserted new layer 27935276f797 after 1c9383292a8f\n - 511136ea3c5a\n - 1c9383292a8f /bin/sh -c #(nop) ADD file:c1472c26527df28498744f9e9e8a8304c\n -> 27935276f797 /bin/sh -c #(squash) from 1c9383292a8f\n - 9942dd43ff21 /bin/sh -c echo '#!/bin/sh' > /usr/sbin/policy-rc.d && echo\n - d92c3c92fa73 /bin/sh -c rm -rf /var/lib/apt/lists/*\n - 0ea0d582fd90 /bin/sh -c sed -i 's/^#\\s*\$deb.*universe\$$/\\1/g' /etc/apt/\n - cc58e55aa5a5 /bin/sh -c apt-get update && apt-get dist-upgrade -y && rm -\n - c4ff7513909d /bin/sh -c #(nop) CMD [/bin/bash]\n - fc294d2b22cb /bin/sh -c apt-get update && apt-get install -y golang-go\n - 8dfc0bb00563 /bin/sh -c #(nop) ADD dir:78239d85b32dd28e4cb1d81ace7ffd32b8\n - 651626d6e364 /bin/sh -c #(nop) WORKDIR /app\n - 589338fba5eb /bin/sh -c go build -o http\n - c50f2b65cab3 /bin/sh -c #(nop) ENV PORT=8000\n - e4eea4411c00 /bin/sh -c #(nop) EXPOSE map[8000/tcp:{}]\n - 63e174c2ca3d /bin/sh -c #(nop) CMD [/app/http]\n - 49b5a7a88d53 /bin/bash\nSquashing from 27935276f797 into 27935276f797\n - Deleting whiteouts\n - Rewriting child history\n - Removing 9942dd43ff21.

You can specify a different\nlayer with the `-from` argument.\n```\n$ docker save | sudo docker-squash -from -t newtag | docker load\n```\nIf you are creating a base image or only want one final squashed layer, you can use the\n`-from root` to squash the base layer and your changes into one layer.\n\n```\n$ docker save | sudo docker-squash -from root -t newtag | docker load\n```\n\n### Development\n\nThis project uses [glock](https://github.com/robfig/glock) for managing 3rd party dependencies.\nYou'll need to install glock into your workspace before hacking on docker-squash.\n\n```\n$ git clone \n$ glock sync github.com/jwilder/docker-squash\n$ make\n```\n\n## License\n\nMIT\n","has_starred","hub_user","immutable_tags_settings",{"_71":11,"_72":73},"enabled","rules",[74],".*","is_automated","permissions",{"_78":17,"_79":11,"_80":11},"read","write","admin","user","storage_size",252479201,"orgData","recentTags",[87],{"_88":40,"_89":90,"_91":92,"_93":94,"_95":96,"_97":98,"_46":113,"_114":90,"_115":29,"_116":52,"_53":117,"_118":119,"_120":104,"_121":113,"_122":61,"_123":17},"content_type","creator",123879,"digest","sha256:40b1577b323d77715144451cb788bfd9c6c186fcfc575e88a549f9b3a4f9ec57","full_size",252442180,"id",159049,"images",[99],{"_100":101,"_91":92,"_102":44,"_103":104,"_105":106,"_107":44,"_108":44,"_109":-5,"_110":111,"_59":61,"_112":-5},"architecture","amd64","features","last_pulled","2026-09-18T05:24:50.823687294Z","last_pushed","2015-11-14T09:52:26Z","os","os_features","os_version","size",252442404,"variant","2015-11-14T09:52:30.942648Z","last_updater","last_updater_username","media_type","latest","repository",190386,"tag_last_pulled","tag_last_pushed","tag_status","v2","sbxKitMetadata","isPotentialSpam","isHubSbxKitsEnabled","displaySecurityMetadata","tagAttestations","tagsHaveAttestations",[],"routes/_layout.r.$namespace.$reponame.tags",{"_34":133,"_140":141,"_129":150,"_151":11},{"_36":134,"_38":135,"_41":42,"_43":44,"_45":11,"_46":47,"_48":49,"_50":136,"_53":31,"_28":29,"_54":55,"_56":-5,"_57":58,"_59":58,"_60":61,"_62":-5,"_63":64,"_65":66,"_67":11,"_68":29,"_69":137,"_75":17,"_76":139,"_81":29,"_82":83},[],[40],[52],{"_71":11,"_72":138},[74],{"_78":17,"_79":11,"_80":11},"tags",{"_142":58,"_143":-5,"_144":-5,"_145":146},"count","next","previous","results",[147],{"_88":40,"_89":90,"_91":92,"_93":94,"_95":96,"_97":148,"_46":113,"_114":90,"_115":29,"_116":52,"_53":117,"_118":119,"_120":104,"_121":113,"_122":61,"_123":17},[149],{"_100":101,"_91":92,"_102":44,"_103":104,"_105":106,"_107":44,"_108":44,"_109":-5,"_110":111,"_59":61,"_112":-5},[],"canDeleteTags","actionData","errors"]
