HA-Redis

HA-Redis is a wrapper around redis that uses ETCD to provide:

• Automatic master election.
• Registers master as service into ETCD in the same format as registrator.
• Automatic querying of host IP:port from docker.

Usage

docker run -d \
    -p ${COREOS_PRIVATE_IPV4}::6379 \
    -v /var/run/docker.sock:/var/run/docker.sock \
    --name redis \
    pulcy/ha-redis:latest \
    --etcd-url http://${COREOS_PRIVATE_IPV4}:4001/pulcy/service/ha-redis/master \
    --container-name redis  \
    --docker-url unix:///var/run/docker.sock

Options

• --announce-ip - Set the IP address to announce under the master key. Only needed when not using --docker-url.
• --announce-port - Set the port number to announce under the master key. Only needed when not using --docker-url.
• --container-name - Name of the docker container running this process.
• --docker-url - URL of the docker daemon to fetch IP/port information from.
• --etcd-url - The host part is used as ETCD address, the path is used as the master key.
• --log-level - Set minimum log level (debug|info|warning|error)
• --master-ttl - TTL of the master key in ETCD.
• --redis-appendonly - If set, append-only mode will be turned on (can also be done in configuration file).
