Redis

基本資訊

Redis 是開源的 記憶體 Key-Value 資料庫實作。

該倉庫位於 https://hub.docker.com/_/redis/，提供了 Redis 3.x 各個版本的映像檔。

使用方法

預設會在 6379 連接埠啟動資料庫。

$ docker run --name some-redis -d redis

另外還可以啟動 持久儲存。

$ docker run --name some-redis -d redis redis-server --appendonly yes

預設資料儲存位置在 VOLUME/data。可以使用 --volumes-from some-volume-container 或 -v /docker/host/dir:/data 將資料存放到本地。

使用其它應用連線到容器，可以用

$ docker run --name some-app --link some-redis:redis -d application-that-uses-redis

或是透過 redis-cli

$ docker run -it --link some-redis:redis --rm redis sh -c 'exec redis-cli -h "$REDIS_PORT_6379_TCP_ADDR" -p "$REDIS_PORT_6379_TCP_PORT"'
