preface
There is little knowledge in this article , Just for the sake of new partners
1. Problem recurrence
*
Create container
2. Interpretation of parameters
-d: Background run container , And return to the container ID;
-i: Run container in interactive mode , Usually associated with -t At the same time ;
-p: Port mapping , The format is ： host ( host ) port : Container port
-t: Reassign a pseudo input terminal to the container , Usually associated with -i At the same time ;
--ip: Develop a fixed ip
--net: Specify network mode
3. Enter the container to view redis.conf file
No, it turns out redis.conf Document's , Then this is the novice step on the pit stage , Because there is no systematic learning docker So it will take a lot of time
2. solve the problem
What about the lack of configuration files ! That's because redis The configuration file inside the container needs to be mapped in when the container is created
Then we need to delete the container we created before , You need to stop the container before deleting it
Stop container ：docker container stop redis-test
Delete container ：docker container rm redis-test
1. Start recreating redis container
docker run -itd --name redis-slave -v
/usr/local/redis/redis.conf:/etc/redis.conf -v
/root/usr/local/redis/data:/data --net mynetwork -p 6381:6379 --ip
172.10.0.3 redis
Parameter interpretation ：
-v /usr/local/redis/redis.conf:/etc/redis.conf： Mapping profile
-v /root/usr/local/redis/data:/data： Mapping data directory
Then there will be redis Configuration file
Build agreed mount external configuration
It's on my host computer redis In the case of , So the host doesn't have one redis The situation
The mapping here is actually mounting external configuration and data installation
1. establish docker Unified external configuration file
mkdir -p docker/redis/{conf,data}
2. stay conf directories creating redis.conf Configuration file for
touch /docker/redis/conf/redis.conf
3. redis.conf The content of the file needs to be downloaded by yourself , A lot online
4. Create startup container , Load the configuration file and persist the data
docker run -d --privileged=true -p 6379:6379 -v
/docker/redis/conf/redis.conf:/etc/redis/redis.conf -v /docker/redis/data:/data
--name redis-test redis redis-server /etc/redis/redis.conf --appendonly yes
Parameter description ：
--privileged=true： In container root Have real root jurisdiction , Otherwise, in the container root External normal user rights only
-v /docker/redis/conf/redis.conf:/etc/redis/redis.conf： Mapping profile
-v /docker/redis/data:/data： Mapping data directory
redis-server /etc/redis/redis.conf： Specify profile startup redis-server process
--appendonly yes： Enable data persistence
There are also some concepts here. Novices may be confused , It will be explained later , Just know how to use it , It's late at night , Good night everyone. !
