## Default admin account

login : admin

password : docker

You should modify this default password with page /ConfigAccounts_p.html when exposing publicly your YaCy container.

## Usage

### First start

#### Most basic

	docker run luccioman/yacy

YaCy web interface is then exposed at http://[container_ip]:8090.	
You can retrieve the container IP address with `docker inspect`.

#### Easier to handle

	docker run --name yacy -p 8090:8090 --log-opt max-size=100m --log-opt max-file=2 luccioman/yacy
	
##### Options detail
	
* --name : allow easier management of your container (without it, docker automatically generate a new name at each startup).
* -p : map host port and container port, allowing web interface access through the usual http://localhost:8090.
* --log-opt max-size : limit maximum docker log file size for this container
* --log-opt max-file : limit number of docker rotated log files for this container

Note : if you do not specify the log related options, when running a YaCy container 24hour a day with default log level, your Docker container log file will grow up to some giga bytes in a few days!

#### Handle persistent data volume

As configured in the Dockerfile, by default yacy data (in /opt/yacy_search_server/DATA) will persist after container stop or deletion, in a volume with an automatically generated id.

But you may map a host directory to hold yacy data in container :

	docker run -v [/your_host/data/directory]:/opt/yacy_search_server/DATA luccioman/yacy
	
Or just use a volume label to help identify it later

	docker run -v yacy_volume:/opt/yacy_search_server/DATA luccioman/yacy

Note that you can list all docker volumes with :

	docker volume ls

#### As background process

	docker run -d luccioman/yacy

### Next starts

#### As attached process

	docker start -a yacy
	
#### As background process

	docker start yacy

### Shutdown

* Use "Shutdown" button in administration web interface
* OR run :

	docker exec [your_container_name] /opt/yacy_search_server/stopYACY.sh
	
### Upgrade

You can upgrade your YaCy container the Docker way with the following commands sequence.

Get latest Docker image :

	docker pull luccioman/yacy:latest
OR 
	docker pull luccioman/yacy:latest-alpine
	
Create new container based on pulled image, using volume data from old container :
	
	docker create --name [tmp-container_name] -p 8090:8090 --volumes-from=[container_name] luccioman/yacy:latest
	
Stop old container :

	docker exec [container_name] /opt/yacy_search_server/stopYACY.sh
	

Start new container :

	docker start [tmp-container_name]
	
Check everything works fine, then you can delete old container :
	
	docker rm [container_name]
	
Rename new container to reuse same container name :

	docker rename [tmp-container_name] [container_name]
