方法一、通过 dockerfile 构建
创建dockerfile
首先，创建目录redis,用于存放后面的相关东西。
w3cschool@w3cschool:~$ mkdir -p ~/redis ~/redis/data
data目录将映射为redis容器配置的/data目录,作为redis数据持久化的存储目录
进入创建的redis目录，创建dockerfile
from debian:jessie
# add our user and group first to make sure their ids get assigned consistently, regardless of whatever dependencies get added
run groupadd -r redis && useradd -r -g redis redis
run apt-get update && apt-get install -y --no-install-recommends \
ca-certificates \
wget \
&& rm -rf /var/lib/apt/lists/*
# grab gosu for easy step-down from root
env gosu_version 1.7
run set -x \
&& wget -o /usr/local/bin/gosu "https://github.com/tianon/gosu/releases/download/$gosu_version/gosu-$(dpkg --print-architecture)" \
&& wget -o /usr/local/bin/gosu.asc "https://github.com/tianon/gosu/releases/download/$gosu_version/gosu-$(dpkg --print-architecture).asc" \
&& export gnupghome="$(mktemp -d)" \
&& gpg --keyserver ha.pool.sks-keyservers.net --recv-keys b42f6819007f00f88e364fd4036a9c25bf357dd4 \
&& gpg --batch --verify /usr/local/bin/gosu.asc /usr/local/bin/gosu \
&& rm -r "$gnupghome" /usr/local/bin/gosu.asc \
&& chmod +x /usr/local/bin/gosu \
&& gosu nobody true
env redis_version 3.2.0
env redis_download_url http://download.redis.io/releases/redis-3.2.0.tar.gz
env redis_download_sha1 0c1820931094369c8cc19fc1be62f598bc5961ca
# for redis-sentinel see: http://redis.io/topics/sentinel
run builddeps='gcc libc6-dev make' \
&& set -x \
&& apt-get update && apt-get install -y $builddeps --no-install-recommends \
&& rm -rf /var/lib/apt/lists/* \
&& wget -o redis.tar.gz "$redis_download_url" \
&& echo "$redis_download_sha1 *redis.tar.gz" | sha1sum -c - \
&& mkdir -p /usr/src/redis \
&& tar -xzf redis.tar.gz -c /usr/src/redis --strip-components=1 \
&& rm redis.tar.gz \
&& make -c /usr/src/redis \
&& make -c /usr/src/redis install \
&& rm -r /usr/src/redis \
&& apt-get purge -y --auto-remove $builddeps
run mkdir /data && chown redis:redis /data
volume /data
workdir /data
copy docker-entrypoint.sh /usr/local/bin/
entrypoint ["docker-entrypoint.sh"]
expose 6379
cmd [ "redis-server" ]
通过dockerfile创建一个镜像，替换成你自己的名字
w3cschool@w3cschool:~/redis$ docker build -t redis:3.2 .
创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像
w3cschool@w3cschool:~/redis$ docker images redis repository tag image id created size redis 3.2 43c923d57784 2 weeks ago 193.9 mb
方法二、docker pull redis:3.2
查找docker hub上的redis镜像
w3cschool@w3cschool:~/redis$ docker search redis name description stars official automated redis redis is an open source ... 2321 [ok] sameersbn/redis 32 [ok] torusware/speedus-redis always updated official ... 29 [ok] bitnami/redis bitnami redis docker image 22 [ok] anapsix/redis 11mb redis server image ... 6 [ok] webhippie/redis docker images for redis 4 [ok] clue/redis-benchmark a minimal docker image t... 3 [ok] williamyeh/redis redis image for docker 3 [ok] unblibraries/redis leverages phusion/baseim... 2 [ok] greytip/redis redis 3.0.3 1 [ok] servivum/redis redis docker image 1 [ok] ...
这里我们拉取官方的镜像,标签为3.2
w3cschool@w3cschool:~/redis$ docker pull redis:3.2
等待下载完成后，我们就可以在本地镜像列表里查到repository为redis,标签为3.2的镜像。
使用redis镜像
运行容器
w3cschool@w3cschool:~/redis$ docker run -p 6379:6379 -v $pwd/data:/data -d redis:3.2 redis-server --appendonly yes 43f7a65ec7f8bd64eb1c5d82bc4fb60e5eb31915979c4e7821759aac3b62f330 w3cschool@w3cschool:~/redis$
命令说明：
-p 6379:6379 :将容器的6379端口映射到主机的6379端口
-v $pwd/data:/data :将主机中当前目录下的data挂载到容器的/data
redis-server --appendonly yes :在容器执行redis-server启动命令，并打开redis持久化配置
查看容器启动情况
w3cschool@w3cschool:~/redis$ docker ps container id image command ... ports names 43f7a65ec7f8 redis:3.2 "docker-entrypoint.sh" ... 0.0.0.0:6379->6379/tcp agitated_cray
连接、查看容器
使用redis镜像执行redis-cli命令连接到刚启动的容器,主机ip为172.17.0.1
w3cschool@w3cschool:~/redis$ docker run -it redis:3.2 redis-cli -h 172.17.0.1 172.17.0.1:6379> info # server redis_version:3.2.0 redis_git_sha1:00000000 redis_git_dirty:0 redis_build_id:f449541256e7d446 redis_mode:standalone os:linux 4.2.0-16-generic x86_64 arch_bits:64 multiplexing_api:epoll ...
