Add Xapiand production ready docker container about xapiand

[Kronuz]

Thank you @cbess.
You can use --name NodeName as a parameter (or it should work) you can also set the XAPIAND_NAME environment variable. The default for the node name in Docker is the host name, so you probably can also request Docker to use a different hostname.

I absolutely agree... but what are the differences in that image, vs our own Docker image?

Current Docker container store index inside container and it lost data when stop or restart container. May be use VOLUME to store index on host machine? Do u have benchmark and get any performance issue with VOLUME in Docker?

As far as I can tell, you can use the -v option to mount the /var/db/xapiand/ directory on the host. It worked for me. However, restarting the container is a different issue:

Node name 6f9e78432364 doesn't match with the one in the cluster's database!

How do I provide the node name upon startup?

Mount option:

-v /my/host/dir/xapiand:/var/db/xapiand

Full example:

docker run -p 8880:8880 -v /my/host/dir/xapiand:/var/db/xapiand --rm dubalu/xapiand:0.22.0 -vvv

BTW, many thanks @Kronuz for sharing this project! I'm loving the potential of seeing a viable and easy to setup ElasticSearch and Sphinxsearch alternative! Great codebase as well!

Awesome, I just tested it, worked perfectly! Thanks for the prompt response. I'm definitely excited to see this project become more visible!

Working command to have persistent Xapiand data in Docker:

docker run -p 8880:8880 -v /tmp/xapiand:/var/db/xapiand --rm dubalu/xapiand:0.22.0 -vvv --name myxapiand

@vit1251 Looks like we don't need any modifications for persistent data.

I think this can be closed out.
