Docker 安装 Redis

方法一、docker pull redis:3.2

查找Docker Hub上的redis镜像

  1. test@docker:~/redis$ docker search  redis
  2. NAME                               DESCRIPTION                          STARS  OFFICIAL  AUTOMATED

  14. ...

这里我们拉取官方的镜像,标签为3.2

  1. test@docker:~/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。

  1. test@docker:~/redis$ docker images redis 
  2. REPOSITORY    TAG        IMAGE ID                CREATED             SIZE
  3. redis               3.2         43c923d57784        2 weeks ago         193.9 MB

方法二、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。

  1. test@docker:~$ 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

  1. FROM debian:jessie
  3. # add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added
  4. RUN groupadd -r redis && useradd -r -g redis redis
  6. RUN apt-get update && apt-get install -y --no-install-recommends \
  7.                 ca-certificates \
  8.                 wget \
  9.         && rm -rf /var/lib/apt/lists/*
  11. # grab gosu for easy step-down from root
  12. ENV GOSU_VERSION 1.7
  13. RUN set -x \
  14.         && wget -O /usr/local/bin/gosu "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-$(dpkg --print-architecture)" \
  15.         && wget -O /usr/local/bin/gosu.asc "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-$(dpkg --print-architecture).asc" \
  16.         && export GNUPGHOME="$(mktemp -d)" \
  17.         && gpg --keyserver ha.pool.sks-keyservers.net --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4 \
  18.         && gpg --batch --verify /usr/local/bin/gosu.asc /usr/local/bin/gosu \
  19.         && rm -r "$GNUPGHOME" /usr/local/bin/gosu.asc \
  20.         && chmod +x /usr/local/bin/gosu \
  21.         && gosu nobody true
  23. ENV REDIS_VERSION 3.2.0
  24. ENV REDIS_DOWNLOAD_URL http://download.redis.io/releases/redis-3.2.0.tar.gz
  25. ENV REDIS_DOWNLOAD_SHA1 0c1820931094369c8cc19fc1be62f598bc5961ca
  27. # for redis-sentinel see: http://redis.io/topics/sentinel
  28. RUN buildDeps='gcc libc6-dev make' \
  29.         && set -x \
  30.         && apt-get update && apt-get install -y $buildDeps --no-install-recommends \
  31.         && rm -rf /var/lib/apt/lists/* \
  32.         && wget -O redis.tar.gz "$REDIS_DOWNLOAD_URL" \
  33.         && echo "$REDIS_DOWNLOAD_SHA1 *redis.tar.gz" | sha1sum -c - \
  34.         && mkdir -p /usr/src/redis \
  35.         && tar -xzf redis.tar.gz -C /usr/src/redis --strip-components=1 \
  36.         && rm redis.tar.gz \
  37.         && make -C /usr/src/redis \
  38.         && make -C /usr/src/redis install \
  39.         && rm -r /usr/src/redis \
  40.         && apt-get purge -y --auto-remove $buildDeps
  42. RUN mkdir /data && chown redis:redis /data
  43. VOLUME /data
  44. WORKDIR /data
  46. COPY docker-entrypoint.sh /usr/local/bin/
  47. ENTRYPOINT ["docker-entrypoint.sh"]
  49. EXPOSE 6379
  50. CMD [ "redis-server" ]

通过Dockerfile创建一个镜像，替换成你自己的名字

  1. test@docker:~/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

  1. test@docker:~/redis$ docker images redis 
  2. REPOSITORY    TAG          IMAGE ID                CREATED             SIZE
  3. redis               3.2           43c923d57784         2 weeks ago        193.9 MB

使用redis镜像

运行容器

  1. test@docker:~/redis$ docker run -p 6379:6379 -v $PWD/data:/data  -d redis:3.2 redis-server --appendonly yes
  2. 43f7a65ec7f8bd64eb1c5d82bc4fb60e5eb31915979c4e7821759aac3b62f330
  3. test@docker:~/redis$

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

  1. test@docker:~/redis$ docker ps
  2. CONTAINER ID   IMAGE        COMMAND                    ...   PORTS                               NAMES
  3. 43f7a65ec7f8    redis:3.2    "docker-entrypoint.sh"  ...   0.0.0.0:6379->6379/tcp     agitated_cr

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

  1. test@docker:~/redis$ docker exec -it 43f7a65ec7f8 redis-cli
  2. 172.17.0.1:6379> info
  3. # Server
  4. redis_version:3.2.0
  5. redis_git_sha1:00000000
  6. redis_git_dirty:0
  7. redis_build_id:f449541256e7d446
  8. redis_mode:standalone
  9. os:Linux 4.2.0-16-generic x86_64
  10. arch_bits:64
  11. multiplexing_api:epoll
