It is a short-term memory for applications.\nMemcached allows to take memory from parts of a system where you have more than you need and make it accessible to areas where you have less than you need.\nRead more on the [memcached website](https://memcached.org/).\n\n## Tags\n\n- `1.5.22-focal`, `1.5.22`, `1.5-focal`, `1.5`, `1-focal`, `1`, `focal`, `beta` - **/!\\ this is a beta release**\n\n\n## Architectures supported\n\n* `amd64`, `arm64`, `ppc64el`, `s390x`\n\n## Usage\n\n### Docker CLI\n\n```sh\n$ docker run -d --name memcached -e TZ=UTC squeakywheel/memcached:edge\n```\n\n#### Parameters\n\n| Parameter | Description |\n|---|---|\n| `-e TZ=UTC` | Timezone. |\n| `-e MEMCACHED_CACHE_SIZE=64MB` | Determines the size of the cache. |\n| `-e MEMCACHED_MAX_CONNECTIONS=1024` | Determines the maximum number of concurrent connections. |\n| `-e MEMCACHED_THREADS=4` | Determines the number of threads to process requests. |\n| `-e MEMCACHED_PASSWORD` | Define the password for the `root` user if another username is provided. By default the authentication is disabled but if this option is passed it becomes enabled. |\n| `-e MEMCACHED_USERNAME` | Define a new user. If this option is passed a password is needed to authenticate the new user. |\n| `-p 11211` | Memcached is exposed inside the container on port `11211`. |\n\n#### Testing/Debugging\n\nIn case you need to debug what it is happening with the container you can run `docker logs `. But if you want to get access to an interactive shell run:\n\n```\n$ docker exec -it /bin/bash\n```\n\n

You can access the memcached instance with telnet from another container (click to expand).

\n\n```sh\n# Create a dedicated network\n$ docker network create memcached-net\n# Connect the main container to it\n$ docker network connect memcached-net memcached\n# Run an interactive container with the latest Ubuntu\n$ docker run -it --rm --name telnet --network memcached-net ubuntu bash\n# Install the telnet cli from within the container\n> apt update && apt install telnet -y\n# Connect to the memcached instance using telnet\n> telnet memcached 11211\nTrying 172.30.0.2...\nConnected to memcached.\nEscape character is '^]'.\n```\nFrom there you can run `memcached` commands, as documented in [their wiki](https://github.com/memcached/memcached/wiki/Commands).\n\n

\n\n```sh\n$ telnet memcached 11211\n```\n\nThere are cases where one might want to pass some memcached command line flags that are not configurable via environment variables. In this case you can pass the flags themselves or a shell script:\n\n```\n$ docker run -d squeakywheel/memcached:edge \n```\n\n### Deploy with Kubernetes\n\nYou can use your favorite Kubernetes distribution; if you don't have one, consider [installing MicroK8s](https://microk8s.io/).\n\nWith microk8s running, enable the `dns` and `storage` add-ons:\n```sh\n$ microk8s enable dns storage\n```\n\nUse the sample deployment yaml provided [here](https://git.launchpad.net/~canonical-server/ubuntu-docker-images/+git/memcached/plain/examples/memcached-deployment.yml).\n\n

Apply the `memcached-deployment.yml` (click to expand)

\n\n```yaml\n# memcached-deployment.yml\n---\napiVersion: apps/v1\nkind: Deployment\nmetadata:\n name: memcached-deployment\nspec:\n replicas: 1\n selector:\n matchLabels:\n app: memcached\n template:\n metadata:\n labels:\n app: memcached\n spec:\n containers:\n - name: memcached\n image: squeakywheel/memcached:edge\n env:\n - name: MEMCACHED_CACHE_SIZE\n value: \"128\"\n - name: MEMCACHED_MAX_CONNECTIONS\n value: \"2048\"\n - name: MEMCACHED_THREADS\n value: \"8\"\n - name: MEMCACHED_USERNAME\n value: \"john\"\n - name: MEMCACHED_PASSWORD\n value: \"pAs$wd\"\n ports:\n - containerPort: 11211\n name: memcached\n protocol: TCP\n```\n

\n\n```\n$ microk8s kubectl apply -f memcached-deployment.yml\n```\n\nMemcached will be listening on port `31211` in your host.\n\n## Bugs and Features request\n\nIf you find a bug in our image or want to request a specific feature file a bug here:\n\nhttps://bugs.launchpad.net/ubuntu-docker-images/+filebug\n\nIn the title of the bug add `memcached: `.\n\nMake sure to include:\n\n* The digest of the image you are using, you can find it using this command replacing `` with the one you used to run the image:\n```sh\n$ docker images --no-trunc --quiet squeakywheel/memcached:\n```\n* Reproduction steps for the deployment\n* If it is a feature request, please provide as much detail as possible\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",2378594172,"orgData","recentTags",[87],{"_88":40,"_89":90,"_91":92,"_93":94,"_95":96,"_46":125,"_126":90,"_127":29,"_128":52,"_53":129,"_130":131,"_132":104,"_133":125,"_134":62,"_135":17},"content_type","creator",10919963,"full_size",136635904,"id",119847989,"images",[97,114,120],{"_98":99,"_100":101,"_102":44,"_103":104,"_105":106,"_107":108,"_109":44,"_110":-5,"_111":112,"_59":62,"_113":-5},"architecture","amd64","digest","sha256:58a194725481386b17a91671e77eafb5e1c6d5c879e1042bbcc7f8f46b38924a","features","last_pulled","2026-09-17T06:24:44.294902786Z","last_pushed","2020-11-24T13:29:31Z","os","linux","os_features","os_version","size",139963392,"variant",{"_98":115,"_100":116,"_102":44,"_103":117,"_105":118,"_107":108,"_109":44,"_110":-5,"_111":119,"_59":62,"_113":-5},"arm64","sha256:b5f1528c8df9e2b2ba52870fa8ad997bfe14d3d14f7f6f1665ca8cc27efa6fee","2026-09-17T06:24:44.264206933Z","2020-11-24T20:33:32Z",131575808,{"_98":121,"_100":122,"_102":44,"_103":123,"_105":124,"_107":108,"_109":44,"_110":-5,"_111":92,"_59":62,"_113":-5},"s390x","sha256:7da36de164db032565bada5dce75d726bb5a19df0a9ba45f796dba0dc9297762","2026-09-17T06:24:44.258860885Z","2020-11-24T13:53:31Z","2020-11-24T20:33:49.084185Z","last_updater","last_updater_username","media_type","edge","repository",9951920,"tag_last_pulled","tag_last_pushed","tag_status","v2","sbxKitMetadata","isPotentialSpam","isHubSbxKitsEnabled","displaySecurityMetadata","tagAttestations","tagsHaveAttestations",[],"routes/_layout.r.$namespace.$reponame.tags",{"_34":145,"_152":153,"_141":164,"_165":11},{"_36":146,"_38":147,"_41":42,"_43":44,"_45":11,"_46":47,"_48":49,"_50":148,"_53":31,"_28":29,"_54":55,"_56":40,"_57":58,"_59":60,"_61":62,"_63":-5,"_64":58,"_65":66,"_67":11,"_68":29,"_69":149,"_75":11,"_76":151,"_81":29,"_82":83},[],[40],[52],{"_71":11,"_72":150},[74],{"_78":17,"_79":11,"_80":11},"tags",{"_154":60,"_155":-5,"_156":-5,"_157":158},"count","next","previous","results",[159],{"_88":40,"_89":90,"_91":92,"_93":94,"_95":160,"_46":125,"_126":90,"_127":29,"_128":52,"_53":129,"_130":131,"_132":104,"_133":125,"_134":62,"_135":17},[161,162,163],{"_98":99,"_100":101,"_102":44,"_103":104,"_105":106,"_107":108,"_109":44,"_110":-5,"_111":112,"_59":62,"_113":-5},{"_98":115,"_100":116,"_102":44,"_103":117,"_105":118,"_107":108,"_109":44,"_110":-5,"_111":119,"_59":62,"_113":-5},{"_98":121,"_100":122,"_102":44,"_103":123,"_105":124,"_107":108,"_109":44,"_110":-5,"_111":92,"_59":62,"_113":-5},[],"canDeleteTags","actionData","errors"]
