The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.\n\n## TL;DR\n\n```console\ndocker run --name memcached REGISTRY_NAME/bitnami/memcached:latest\n```\n\n> Note: You need to substitute the `REGISTRY_NAME` placeholder with a reference to your container registry.\n\n## How to deploy Memcached in Kubernetes\n\nDeploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the [Bitnami Memcached Chart GitHub repository](https://github.com/bitnami/charts/tree/master/bitnami/memcached).\n\n## Why use a non-root container?\n\nNon-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers [in our docs](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-work-with-non-root-containers-index.html).\n\n## Supported tags and respective `Dockerfile` links\n\nLearn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags [in our documentation page](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-understand-rolling-tags-containers-index.html).\n\n## Get this image\n\nThe recommended way to get the Bitnami Memcached Docker Image is to pull the prebuilt image from the [Docker Hub Registry](https://hub.docker.com).\n\n```console\ndocker pull REGISTRY_NAME/bitnami/memcached:latest\n```\n\nTo use a specific version, you can pull a versioned tag. You can view the [list of available versions](https://hub.docker.com/r/bitnami/memcached/tags/) in the Docker Hub Registry.\n\n```console\ndocker pull REGISTRY_NAME/bitnami/memcached:[TAG]\n```\n\nIf you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the `docker build` command. Remember to replace the `APP`, `VERSION` and `OPERATING-SYSTEM` path placeholders in the example command below with the correct values.\n\n```console\ngit clone https://github.com/bitnami/containers.git\ncd bitnami/APP/VERSION/OPERATING-SYSTEM\ndocker build -t REGISTRY_NAME/bitnami/APP:latest .\n```\n\n## Using `docker-compose.yaml`\n\nPlease be aware this file has not undergone internal testing. Consequently, we advise its use exclusively for development or testing purposes. For production-ready deployments, we highly recommend utilizing its associated [Bitnami Helm chart](https://github.com/bitnami/charts/tree/main/bitnami/memcached).\n\n## Connecting to other containers\n\nUsing [Docker container networking](https://docs.docker.com/engine/userguide/networking/), a Memcached server running inside a container can easily be accessed by your application containers.\n\nContainers attached to the same network can communicate with each other using the container name as the host name.\n\n## Configuration\n\nThe following sections describe environment variables and related settings.\n\n### Environment variables\n\nThe following tables list the main variables you can set.\n\n#### Customizable environment variables\n\n| Name | Description | Default Value |\n|-----------------------------|------------------------------------------------------------------------|---------------|\n| `MEMCACHED_LISTEN_ADDRESS` | Host that the Memcached service will bind to. | `nil` |\n| `MEMCACHED_PORT_NUMBER` | Port number used by Memcached. | `11211` |\n| `MEMCACHED_USERNAME` | Memcached admin username. | `root` |\n| `MEMCACHED_PASSWORD` | Password for the Memcached admin user. | `nil` |\n| `MEMCACHED_MAX_ITEM_SIZE` | Memcached maximum item size. | `nil` |\n| `MEMCACHED_EXTRA_FLAGS` | Extra flags to be used when running Memcached. | `nil` |\n| `MEMCACHED_MAX_TIMEOUT` | Maximum timeout in seconds for Memcached to start or stop. | `5` |\n| `MEMCACHED_CACHE_SIZE` | Memcached cache size in MB. | `nil` |\n| `MEMCACHED_MAX_CONNECTIONS` | Maximum amount of concurrent connections that Memcached will tolerate. | `nil` |\n| `MEMCACHED_THREADS` | Amount of process threads that Memcached will use. | `nil` |\n\n#### Read-only environment variables\n\n| Name | Description | Value |\n|------------------------------|---------------------------------------------|--------------------------------------|\n| `MEMCACHED_BASE_DIR` | Memcached installation directory. | `${BITNAMI_ROOT_DIR}/memcached` |\n| `MEMCACHED_CONF_DIR` | Memcached configuration directory. | `${MEMCACHED_BASE_DIR}/conf` |\n| `MEMCACHED_DEFAULT_CONF_DIR` | Memcached configuration directory. | `${MEMCACHED_BASE_DIR}/conf.default` |\n| `MEMCACHED_BIN_DIR` | Memcached directory for binary executables. | `${MEMCACHED_BASE_DIR}/bin` |\n| `SASL_CONF_PATH` | Memcached SASL configuration directory. | `${MEMCACHED_CONF_DIR}/sasl2` |\n| `SASL_CONF_FILE` | Memcached SASL configuration | `${SASL_CONF_PATH}/memcached.conf` |\n| `SASL_DB_FILE` | Memcached SASL database file. | `${SASL_CONF_PATH}/memcachedsasldb` |\n| `MEMCACHED_DAEMON_USER` | Memcached system user. | `memcached` |\n| `MEMCACHED_DAEMON_GROUP` | Memcached system group. | `memcached` |\n\n### Specify the cache size\n\nBy default, the Bitnami Memcached container will not specify any cache size and will start with Memcached defaults (64MB). You can specify a different value with the `MEMCACHED_CACHE_SIZE` environment variable (in MB).\n\n### Specify maximum number of concurrent connections\n\nBy default, the Bitnami Memcached container will not specify any maximum number of concurrent connections and will start with Memcached defaults (1024 concurrent connections). You can specify a different value with the `MEMCACHED_MAX_CONNECTIONS` environment variable.\n\n### Specify number of threads to process requests\n\nBy default, the Bitnami Memcached container will not specify the amount of threads for which to process requests for and will start with Memcached defaults (4 threads). You can specify a different value with the `MEMCACHED_THREADS` environment variable.\n\n### Specify max item size (slab size)\n\nBy default, the Memcached container will not specify any max item size and will start with Memcached defaults (1048576 ~ 1 megabyte). You can specify a different value with the `MEMCACHED_MAX_ITEM_SIZE` environment variable. Only numeric values are accepted - use `8388608` instead of `8m`\n\n### Creating the Memcached admin user\n\nAuthentication on the Memcached server is disabled by default. To enable authentication, specify the password for the Memcached admin user using the `MEMCACHED_PASSWORD` environment variable (or in the content of the file specified in `MEMCACHED_PASSWORD_FILE`).\n\nTo customize the username of the Memcached admin user, which defaults to `root`, the `MEMCACHED_USERNAME` variable should be specified.\n\n> **NOTE** The default value of the `MEMCACHED_USERNAME` is `root`.\n\n### Passing extra command-line flags to memcached\n\nPassing extra command-line flags to the Memcached service command is possible by adding them as arguments to *run.sh* script:\n\n```console\ndocker run --name memcached REGISTRY_NAME/bitnami/memcached:latest /opt/bitnami/scripts/memcached/run.sh -vvv\n```\n\nAlternatively, modify the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/memcached/docker-compose.yml) file present in this repository:\n\n```yaml\nservices:\n memcached:\n ...\n command: /opt/bitnami/scripts/memcached/run.sh -vvv\n ...\n```\n\nRefer to the [Memcached man page](https://www.unix.com/man-page/linux/1/memcached/) for the complete list of arguments.\n\n### Using custom SASL configuration\n\nIn order to load your own SASL configuration file, you will have to make them available to the container. You can do it doing the following:\n\n- Mounting a volume with your custom configuration\n- Adding custom configuration via environment variable.\n\nBy default, when authentication is enabled the SASL configuration of Memcached is written to `/opt/bitnami/memcached/sasl2/memcached.conf` file with the following content:\n\n```config\nmech_list: plain\nsasldb_path: /opt/bitnami/memcached/conf/memcachedsasldb\n```\n\nThe `/opt/bitnami/memcached/conf/memcachedsasldb` is the path to the `sasldb` file that contains the list of Memcached users.\n\n### FIPS configuration in Bitnami Secure Images\n\nThe Bitnami Memcached Docker image from the [Bitnami Secure Images](https://go-vmware.broadcom.com/contact-us) catalog includes extra features and settings to configure the container with FIPS capabilities. You can configure the next environment variables:\n\n- `OPENSSL_FIPS`: whether OpenSSL runs in FIPS mode or not. `yes` (default), `no`.\n\n## Logging\n\nThe Bitnami Memcached Docker image sends the container logs to the `stdout`. To view the logs:\n\n```console\ndocker logs memcached\n```\n\nor using Docker Compose:\n\n```console\ndocker-compose logs memcached\n```\n\nYou can configure the containers [logging driver](https://docs.docker.com/engine/admin/logging/overview/) using the `--log-driver` option if you wish to consume the container logs differently. In the default configuration docker uses the `json-file` driver.\n\n## Notable changes\n\nThe following subsections describe notable changes.\n\n### 1.5.18-debian-9-r13 and 1.5.19-ol-7-r1\n\n- Fixes regression in Memcached Authentication introduced in release `1.5.18-debian-9-r6` and `1.5.18-ol-7-r7` (#62).\n\n### 1.5.18-debian-9-r6 and 1.5.18-ol-7-r7\n\n- Decrease the size of the container. The configuration logic is now based on Bash scripts in the `rootfs/` folder.\n- Custom SASL configuration should be mounted at `/opt/bitnami/memcached/conf/sasl2/` instead of `/bitnami/memcached/conf/`.\n- Password for Memcached admin user can be specified in the content of the file specified in `MEMCACHED_PASSWORD_FILE`.\n\n### 1.5.0-r1\n\n- The Memcached container has been migrated to a non-root container approach. Previously the container run as `root` user and the Memcached daemon was started as `memcached` user. From now on, both the container and the Memcached daemon run as user `1001`.\n As a consequence, the user running the Memcached process can write to the configuration files.\n\n### 1.4.25-r4\n\n- `MEMCACHED_USER` parameter has been renamed to `MEMCACHED_USERNAME`.\n\n### 1.4.25-r0\n\n- The logs are always sent to the `stdout` and are no longer collected in the volume.\n\n## License\n\nCopyright © 2026 Broadcom.
