Docker 安裝 Redis

方法一、通過 Dockerfile 構建

建立Dockerfile

首先，建立目錄redis,用於存放後面的相關東西。

[email protected]:~$ mkdir -p ~/redis ~/redis/data

data目錄將對映為redis容器配置的/data目錄,作為redis資料持久化的儲存目錄

進入建立的redis目錄，建立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" ]
 

通過Dockerfile建立一個映象，替換成你自己的名字

[email protected]:~/redis$ docker build  -t redis:3.2.

建立完成後，我們可以在本地的映象列表裡查詢到剛剛建立的映象

[email protected]:~/redis$ docker images redis 
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
redis               3.243c923d577842 weeks ago         
 
193.9 MB

方法二、docker pull redis:3.2

查詢Docker Hub上的redis映象

[email protected]:~/redis$ docker search  redis

這裡我們拉取官方的映象,標籤為3.2

[email protected]:~/redis$ docker pull  redis:3.2

等待下載完成後，我們就可以在本地映象列表裡查到REPOSITORY為redis,標籤為3.2的映象。

使用redis映象

執行容器

[email protected]:~/redis$ docker run -p 6379:6379 -v $PWD/data:/data  -d redis:3.2 redis-server --appendonly yes
43f7a65ec7f8bd64eb1c5d82bc4fb60e5eb31915979c4e7821759aac3b62f330
[email protected]:~/redis$

命令說明：

-p 6379:6379 : 將容器的6379埠對映到主機的6379埠

-v $PWD/data:/data : 將主機中當前目錄下的data掛載到容器的/data

redis-server --appendonly yes : 在容器執行redis-server啟動命令，並開啟redis持久化配置

檢視容器啟動情況

[email protected]:~/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

連線、檢視容器

使用redis映象執行redis-cli命令連線到剛啟動的容器,主機IP為172.17.0.1

[email protected]:~/redis$ docker exec-it 43f7a65ec7f8 redis-cli
