Docker Memcached CentOS 6.6 + Memcached 1.4.22 Docker Image

My first succesful Docker image build that seems to work in communicating with the host system

• Github repository with Dockerfile github.com/centminmod/docker-centos66-memcached
• Docker Hub repo registry.hub.docker.com/u/centminmod/docker-centos66-memcached/
• Quay.io repo quay.io/repository/centminmod/docker-centos66-memcached

Grab the docker image from my repository

Code:

docker pull centminmod/docker-centos66-memcached

Run docker container specifying a name e.g. memc1 mapping local:docker ports to 11211

Code:

docker run --name memc1 -d -p 11211:11211 -t centminmod/docker-centos66-memcached

If you run Centmin Mod's Memcached server on host system, you'd need to stop that Memcached server instance or bind local port to something other than 11211 e.g. 33211:11211.

Code:

docker run --name memc1 -d -p 33211:11211 -t centminmod/docker-centos66-memcached

Checking to see the process running in docker container named memc1

Code:

docker top memc1

On the host system

Testing host system connection to Memcached docker container on port 11211 and server's ip address (not localhost nor 127.0.0.1).

@Guilherme Jaccoud how does one attach their Dockerfile to Docker Hub repo listing that I see some repos have centminmod/centos66-memcached Repository ??

 

Run some Twitter Twemperf aka mcperf memcached server benchmarks with 5000 connections and 20k connection rate. As expected host built via Centmin Mod LEMP stack's Memcached server performs better than Docker container based Memcached server. Centmin Mod LEMP's Memcached version is sourced compiled with igbinary support as well while docker version is just a YUM installed version via Remi repository.

Run some memtier_benchmarks against both Docker built Memcached server and Centmin Mod LEMP default Memcached servers again same 1.4.22 and settings.

Much larger performance lead goes to Centmin Mod's Memcached instance 66% faster than Docker built instance !

Try launching 3x Memcached server docker containers named, memc1, memc2 and memc3 for some load balanced auto cache sharding Memcached pool benchmarks. Of course expected it won't scale much seeing as all Memcached instances are coming from same local network as opposed to remote Memcached server instances.

Launching the 3x Memcached docker container instances mapping local ports 33210, 33211, 33212 against docker 11211.

Code:

docker run --name memc1 -d -p 33210:11211 -t centminmod/centos66-memcached
docker run --name memc2 -d -p 33211:11211 -t centminmod/centos66-memcached
docker run --name memc3 -d -p 33212:11211 -t centminmod/centos66-memcached

docker ps

Code:

Twemperf memcached benchmarks against load balanced 3xMemcached server pools listening on port 44123.

Look at the total memcached connection stats for the Memcached pool compared to stand alone Memcached on non-docker and docker instances and you can see why my custom auto shared Memcached pooling tests can scale much higher for high concurrent connection based Memcached traffic. Some I reserve for my paid private consulting clients if they need such

Also notice total items in Memcached pools for each server is roughly shared and divided amongst all 3x Memcached docker instances

Connection rate and request and response rate slightly better than single Memcached docker instance. However, nice boost for 3x Memcached docker pool in terms of connection time (avg 271.1ms vs 341.1ms), connect time (avg 3.6ms vs 55ms), and response time @99.9 percentile (47ms vs 65ms).

Webhooks and services on Github repos ?

 

Yeah I figured Memcached would be the easier to make a docker image on and would be most used. That and Redis - will be doing a Redis Docker image just to see as I have been benchmarking Memcached and Redis servers in standalone and auto shard cached multiple server pool configs

 

Cool, got to look into this.. as I did Github and Docker Hub repos manually for both heh

found it





hmm do automatic builds override manually pushed builds with and without tags ? or is automated builds tagged with latest only tag ?

 

Sweet my first automated Docker Hub build repo centminmod/docker-centos66-memcached

 

Thanks for the heads up will check that out. Docker is fun.. shame performance can be slower. But I guess you need to benchmark Docker containers to make sure they perform reasonably in real world use

 

Made a CentOS 7 Memcached Docker version too Docker Memcached - CentOS 7.0 + Memcached 1.4.22 Docker Image | Centmin Mod Community

 

wrong thread ? Docker Discuss - Project Atomic any users ? | Centmin Mod Community
