Exploring Redis with Docker

Start a new container running Redis

docker run -d -p 6379:6379 --name redis1 redis
# Run the Redis CLI in the container
docker exec -it redis1 sh
# redis-cli
127.0.0.1:6379> set name mark
OK
127.0.0.1:6379> get name
"mark"
127.0.0.1:6379> incr counter
(integer) 1
127.0.0.1:6379> incr counter
(integer) 2
127.0.0.1:6379> get counter
"2"
127.0.0.1:6379> exit
# exit

Connect from another linked container

docker run -it --rm --link redis1:redis --name client1 redis sh
# redis-cli -h redis
redis:6379>
redis:6379> get name
"mark"
redis:6379> get counter
"2"
redis:6379> exit
# exit
