run couch with existing couchdb files.

[kavinho]

Hi, this is a question : How can I use already existing, locally hosted couchdb data files(v 2.1), using this docker image. While this works in real world by simply copying /shards and _dbs.couch into the new couch instance, it does not work on docker- hosted couch db. IT basically fails to load dbs. and the web-console verify fails , when trying to create a test db.
sample command :
docker run -d -v $(pwd)/my-couch-files:/opt/couchdb/data -p 5984:5984 --name mw-couch apache/couchdb:latest
docker log output :

You also need to mount with docker run -v your ini file directory. The reason is that the shard files have embedded within them the name of the local node and its hostname, which is specified in etc/vm.args as -name <nodename>@<hostname-or-ip>. The default file in the container must not match what you used in your locally running CouchDB instance.
