Let us learn more about memcached docker environment variables. With the help of our Docker hosting support services at Bobcares, we will now learn more about the usage of environment variables.

Using environment variables to configure settings: Memcached inside a Docker container

While running Memcached within a Docker container, we may utilize environment variables to specify different Memcached service parameters.

The following are some popular environment variables for setting up a Docker container:

1. MEMCACHED_MEMORY_LIMIT. This environment variable specifies the maximum amount of RAM available to Memcached for data caching. MEMCACHED MEMORY LIMIT=512m, for example, limits Memcached to 512 megabytes of memory.
2. MEMCACHED_THREADS. This environment variable specifies the number of threads that Memcached can employ to handle requests. Set MEMCACHED THREADS=4 to use 4 threads, for example.
3. MEMCACHED_MAX_CONNECTIONS. This environment variable specifies the maximum number of concurrent connections that Memcached can tolerate. MEMCACHED MAX CONNECTIONS=1024, for example, allows up to 1024 connections.
4. MEMCACHED_TCP_PORT. This environment variable specifies the port on which Memcached will listen for incoming TCP connections. To listen on the default port, for example, we may set MEMCACHED TCP PORT=11211.
5. MEMCACHED_UDP_PORT. This environment variable specifies the port on which Memcached will listen for incoming UDP connections. To listen on the default port, for example, we may set MEMCACHED UDP PORT=11211.
6. MEMCACHED_EXTRA_FLAGS. This environment variable specifies any additional flags that Memcached should be supplied when it starts up. To enable verbose logging, for example, we may set MEMCACHED EXTRA FLAGS=-v.

The -e option may be used to set these environment variables when executing the Memcached Docker container. For example, to launch a Memcached container with a memory limit of 512 MB, use the following command:

docker run -e MEMCACHED_MEMORY_LIMIT=512m memcached

We can simply customize numerous settings related to the Memcached service operating within a Docker container using environment variables, making it more versatile and adaptable to varied environments and use cases.
