介绍

Docker Compose 是官方编排的项目之一，负责快速的部署分布式应用。

使用Docker Compose可以轻松、高效的管理容器，它是一个用户定义和运行多个容器的Docker应用程序。

在Docker Compose中你可以使用YAML文件来配置你的应用服务，然后只需要一个简单的命令，就可以创建并启动你配置的所有服务。

实验设备及需求

• 前后端项目一份（Vue+spring）

• Ubuntu（已装docker及docker-compose）

一、文件目录总览

目录文件夹如下:

• 前端：nginx部署

• 后端：Java8环境运行jar包

• 数据库：mysql、redis

为了让其他同学更好的理解创建过程，以后能够写出适合自己的，以下会分模块进行粗略解释，完整代码可见第六点。

二、前端Nginx

前端项目中ip地址改为宿主机ip地址，npm run build打包前端代码放入指定路径中

docker-compose.yml文件中的:符号，前面的路径/端口表示宿主机的（自定义），后面的路径/端口表示容器的（基本不用修改）

docker-compose内前端服务

nginx:
    image: nginx:latest
    container_name: nginx
    restart: always
    volumes:
      - ./config/nginx/nginx.conf:/etc/nginx/nginx.conf   # nginx配置文件
      - ./config/html/dist/:/usr/share/nginx/html/        # 前端打包文件
    ports:
      - "8080:80"
    networks:
      data_security:
        ipv4_address: 10.1.0.8
    privileged: true      # 这个必须要，解决nginx的文件调用的权限问题

nginx.conf

worker_processes  1;

events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;

        location / {
            root   /usr/share/nginx/html;
            try_files $uri $uri/ /index.html last; # 在原来的文件中添加这句
            index  index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
    }
}

三、数据库Mysql、Redis

docker-compose内数据库服务

mysql:
    image: mysql:8.0.12
    container_name: mysql
    restart: always
    environment:
      - TZ=Asia/Shanghai
      - MYSQL_ROOT_PASSWORD=123456                #数据库初始话为root用户设置的默认密码
      - MYSQL_DATABASE=xx						# 项目数据库名
      # - MYSQL_USER:                           #自定义数据库的用户，权限只作用于MYSQL_DATABASE配置的数据库
      # - MYSQL_PASSWORD:                    #自定义数据库的用户，权限只作用于MYSQL_DATABASE配置的数据库
    volumes:
      # - ./config/mysql/cnf/my.cnf:/etc/my.cnf
      # - ./config/mysql/data:/var/lib/mysql
      - ./config/mysql/init/xx.sql:/docker-entrypoint-initdb.d/xx.sql		# 自己的sql文件
    ports:
      - "3306:3306"
    networks:
      data_security:
        ipv4_address: 10.1.0.2
    command: --default-authentication-plugin=mysql_native_password --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci --sql-mode='' --max-execution-time=1000

redis:
    image: redis:latest
    container_name: redis
    restart: always
    environment:
      - TZ=Asia/Shanghai
      - REDIS_ROOT_PASSWORD=passwd
    volumes:
      - ./config/redis/conf/redis.conf:/etc/redis/redis.conf   #挂载redis.conf不然后续重启redis密码会失效
      - ./config/redis/data:/data
      # - ./config/redis/log/redis.log:/logs/redis.log
    ports:
      - "6379:6379"
    networks:
      data_security:
        ipv4_address: 10.1.0.3
    # privileged: true
    command: redis-server /etc/redis/redis.conf --requirepass passwd          #指定配置文件启动redis

mysql命令command中：

命令	描述
--default-authentication-plugin=mysql_native_password	默认的身份认证插件
--character-set-server=utf8mb4	将MySQL数据库相关的字符集都设置为utf8mb4
--sql-mode=''	默认值为空，此时MySQL执行的不严格的检查
--max-execution-time=1000	最大执行时间

项目中没有配置redis的可以跳过了。

Redis配置文件redis.conf

# Redis配置文件样例

# Redis默认不是以守护进程的方式运行，可以通过该配置项修改，使用yes启用守护进程
# 启用守护进程后，Redis会把pid写到一个pidfile中，在/var/run/redis.pid
daemonize no

# 当Redis以守护进程方式运行时，Redis默认会把pid写入/var/run/redis.pid文件，可以通过pidfile指定
pidfile /var/run/redis.pid

# 指定Redis监听端口，默认端口为6379
# 如果指定0端口，表示Redis不监听TCP连接
port 6379

# 绑定的主机地址
# 你可以绑定单一接口，如果没有绑定，所有接口都会监听到来的连接
# bind 0.0.0.0
# 2、关闭保护机制
protected-mode no

# Specify the path for the unix socket that will be used to listen for
# incoming connections. There is no default, so Redis will not listen
# on a unix socket when not specified.
#
# unixsocket /tmp/redis.sock
# unixsocketperm 755

# 当客户端闲置多长时间后关闭连接，如果指定为0，表示关闭该功能
timeout 0

# 指定日志记录级别，Redis总共支持四个级别：debug、verbose、notice、warning，默认为verbose
# debug (很多信息, 对开发／测试比较有用)
# verbose (many rarely useful info, but not a mess like the debug level)
# notice (moderately verbose, what you want in production probably)
# warning (only very important / critical messages are logged)
loglevel verbose

# 日志记录方式，默认为标准输出，如果配置为redis为守护进程方式运行，而这里又配置为标准输出，则日志将会发送给/dev/null
logfile ""

# To enable logging to the system logger, just set 'syslog-enabled' to yes,
# and optionally update the other syslog parameters to suit your needs.
# syslog-enabled no

# Specify the syslog identity.
# syslog-ident redis

# Specify the syslog facility.  Must be USER or between LOCAL0-LOCAL7.
# syslog-facility local0

# 设置数据库的数量，默认数据库为0，可以使用select <dbid>命令在连接上指定数据库id
# dbid是从0到‘databases’-1的数目
databases 16

################################ SNAPSHOTTING  #################################
# 指定在多长时间内，有多少次更新操作，就将数据同步到数据文件，可以多个条件配合
# Save the DB on disk:
#
#   save <seconds> <changes>
#
#   Will save the DB if both the given number of seconds and the given
#   number of write operations against the DB occurred.
#
#   满足以下条件将会同步数据:
#   900秒（15分钟）内有1个更改
#   300秒（5分钟）内有10个更改
#   60秒内有10000个更改
#   Note: 可以把所有“save”行注释掉，这样就取消同步操作了

save 900 1
save 300 10
save 60 10000

# 指定存储至本地数据库时是否压缩数据，默认为yes，Redis采用LZF压缩，如果为了节省CPU时间，可以关闭该选项，但会导致数据库文件变的巨大
rdbcompression yes

# 指定本地数据库文件名，默认值为dump.rdb
dbfilename dump.rdb

# 工作目录.
# 指定本地数据库存放目录，文件名由上一个dbfilename配置项指定
#
# Also the Append Only File will be created inside this directory.
#
# 注意，这里只能指定一个目录，不能指定文件名
dir ./

################################# REPLICATION #################################

# 主从复制。使用slaveof从 Redis服务器复制一个Redis实例。注意，该配置仅限于当前slave有效
# so for example it is possible to configure the slave to save the DB with a
# different interval, or to listen to another port, and so on.
# 设置当本机为slav服务时，设置master服务的ip地址及端口，在Redis启动时，它会自动从master进行数据同步
# slaveof <masterip> <masterport>

# 当master服务设置了密码保护时，slav服务连接master的密码
# 下文的“requirepass”配置项可以指定密码
# masterauth <master-password>

# When a slave lost the connection with the master, or when the replication
# is still in progress, the slave can act in two different ways:
#
# 1) if slave-serve-stale-data is set to 'yes' (the default) the slave will
#    still reply to client requests, possibly with out of data data, or the
#    data set may just be empty if this is the first synchronization.
#
# 2) if slave-serve-stale data is set to 'no' the slave will reply with
#    an error "SYNC with master in progress" to all the kind of commands
#    but to INFO and SLAVEOF.
#
slave-serve-stale-data yes

# Slaves send PINGs to server in a predefined interval. It's possible to change
# this interval with the repl_ping_slave_period option. The default value is 10
# seconds.
#
# repl-ping-slave-period 10

# The following option sets a timeout for both Bulk transfer I/O timeout and
# master data or ping response timeout. The default value is 60 seconds.
#
# It is important to make sure that this value is greater than the value
# specified for repl-ping-slave-period otherwise a timeout will be detected
# every time there is low traffic between the master and the slave.
#
# repl-timeout 60

################################## SECURITY ###################################

# Warning: since Redis is pretty fast an outside user can try up to
# 150k passwords per second against a good box. This means that you should
# use a very strong password otherwise it will be very easy to break.
# 设置Redis连接密码，如果配置了连接密码，客户端在连接Redis时需要通过auth <password>命令提供密码，默认关闭
requirepass passwd
# Command renaming.
#
# It is possilbe to change the name of dangerous commands in a shared
# environment. For instance the CONFIG command may be renamed into something
# of hard to guess so that it will be still available for internal-use
# tools but not available for general clients.
#
# Example:
#
# rename-command CONFIG b840fc02d524045429941cc15f59e41cb7be6c52
#
# It is also possilbe to completely kill a command renaming it into
# an empty string:
#
# rename-command CONFIG ""

################################### LIMITS ####################################

# 设置同一时间最大客户端连接数，默认无限制，Redis可以同时打开的客户端连接数为Redis进程可以打开的最大文件描述符数，
# 如果设置maxclients 0，表示不作限制。当客户端连接数到达限制时，Redis会关闭新的连接并向客户端返回max Number of clients reached错误信息
# maxclients 128

# Don't use more memory than the specified amount of bytes.
# When the memory limit is reached Redis will try to remove keys with an
# EXPIRE set. It will try to start freeing keys that are going to expire
# in little time and preserve keys with a longer time to live.
# Redis will also try to remove objects from free lists if possible.
#
# If all this fails, Redis will start to reply with errors to commands
# that will use more memory, like SET, LPUSH, and so on, and will continue
# to reply to most read-only commands like GET.
#
# WARNING: maxmemory can be a good idea mainly if you want to use Redis as a
# 'state' server or cache, not as a real DB. When Redis is used as a real
# database the memory usage will grow over the weeks, it will be obvious if
# it is going to use too much memory in the long run, and you'll have the time
# to upgrade. With maxmemory after the limit is reached you'll start to get
# errors for write operations, and this may even lead to DB inconsistency.
# 指定Redis最大内存限制，Redis在启动时会把数据加载到内存中，达到最大内存后，Redis会先尝试清除已到期或即将到期的Key，
# 当此方法处理后，仍然到达最大内存设置，将无法再进行写入操作，但仍然可以进行读取操作。
# Redis新的vm机制，会把Key存放内存，Value会存放在swap区
# maxmemory <bytes>

# MAXMEMORY POLICY: how Redis will select what to remove when maxmemory
# is reached? You can select among five behavior:
#
# volatile-lru -> remove the key with an expire set using an LRU algorithm
# allkeys-lru -> remove any key accordingly to the LRU algorithm
# volatile-random -> remove a random key with an expire set
# allkeys->random -> remove a random key, any key
# volatile-ttl -> remove the key with the nearest expire time (minor TTL)
# noeviction -> don't expire at all, just return an error on write operations
#
# Note: with all the kind of policies, Redis will return an error on write
#       operations, when there are not suitable keys for eviction.
#
#       At the date of writing this commands are: set setnx setex append
#       incr decr rpush lpush rpushx lpushx linsert lset rpoplpush sadd
#       sinter sinterstore sunion sunionstore sdiff sdiffstore zadd zincrby
#       zunionstore zinterstore hset hsetnx hmset hincrby incrby decrby
#       getset mset msetnx exec sort
#
# The default is:
#
# maxmemory-policy volatile-lru

# LRU and minimal TTL algorithms are not precise algorithms but approximated
# algorithms (in order to save memory), so you can select as well the sample
# size to check. For instance for default Redis will check three keys and
# pick the one that was used less recently, you can change the sample size
# using the following configuration directive.
#
# maxmemory-samples 3

############################## APPEND ONLY MODE ###############################

#
# Note that you can have both the async dumps and the append only file if you
# like (you have to comment the "save" statements above to disable the dumps).
# Still if append only mode is enabled Redis will load the data from the
# log file at startup ignoring the dump.rdb file.
# 指定是否在每次更新操作后进行日志记录，Redis在默认情况下是异步的把数据写入磁盘，如果不开启，可能会在断电时导致一段时间内的数据丢失。
# 因为redis本身同步数据文件是按上面save条件来同步的，所以有的数据会在一段时间内只存在于内存中。默认为no
# IMPORTANT: Check the BGREWRITEAOF to check how to rewrite the append
# log file in background when it gets too big.

appendonly no

# 指定更新日志文件名，默认为appendonly.aof
# appendfilename appendonly.aof

# The fsync() call tells the Operating System to actually write data on disk
# instead to wait for more data in the output buffer. Some OS will really flush
# data on disk, some other OS will just try to do it ASAP.

# 指定更新日志条件，共有3个可选值：
# no:表示等操作系统进行数据缓存同步到磁盘（快）
# always:表示每次更新操作后手动调用fsync()将数据写到磁盘（慢，安全）
# everysec:表示每秒同步一次（折衷，默认值）

appendfsync everysec
# appendfsync no

# When the AOF fsync policy is set to always or everysec, and a background
# saving process (a background save or AOF log background rewriting) is
# performing a lot of I/O against the disk, in some Linux configurations
# Redis may block too long on the fsync() call. Note that there is no fix for
# this currently, as even performing fsync in a different thread will block
# our synchronous write(2) call.
#
# In order to mitigate this problem it's possible to use the following option
# that will prevent fsync() from being called in the main process while a
# BGSAVE or BGREWRITEAOF is in progress.
#
# This means that while another child is saving the durability of Redis is
# the same as "appendfsync none", that in pratical terms means that it is
# possible to lost up to 30 seconds of log in the worst scenario (with the
# default Linux settings).
#
# If you have latency problems turn this to "yes". Otherwise leave it as
# "no" that is the safest pick from the point of view of durability.
no-appendfsync-on-rewrite no

# Automatic rewrite of the append only file.
# Redis is able to automatically rewrite the log file implicitly calling
# BGREWRITEAOF when the AOF log size will growth by the specified percentage.
#
# This is how it works: Redis remembers the size of the AOF file after the
# latest rewrite (or if no rewrite happened since the restart, the size of
# the AOF at startup is used).
#
# This base size is compared to the current size. If the current size is
# bigger than the specified percentage, the rewrite is triggered. Also
# you need to specify a minimal size for the AOF file to be rewritten, this
# is useful to avoid rewriting the AOF file even if the percentage increase
# is reached but it is still pretty small.
#
# Specify a precentage of zero in order to disable the automatic AOF
# rewrite feature.

auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb

################################## SLOW LOG ###################################

# The Redis Slow Log is a system to log queries that exceeded a specified
# execution time. The execution time does not include the I/O operations
# like talking with the client, sending the reply and so forth,
# but just the time needed to actually execute the command (this is the only
# stage of command execution where the thread is blocked and can not serve
# other requests in the meantime).
#
# You can configure the slow log with two parameters: one tells Redis
# what is the execution time, in microseconds, to exceed in order for the
# command to get logged, and the other parameter is the length of the
# slow log. When a new command is logged the oldest one is removed from the
# queue of logged commands.

# The following time is expressed in microseconds, so 1000000 is equivalent
# to one second. Note that a negative number disables the slow log, while
# a value of zero forces the logging of every command.
slowlog-log-slower-than 10000

# There is no limit to this length. Just be aware that it will consume memory.
# You can reclaim memory used by the slow log with SLOWLOG RESET.
slowlog-max-len 1024

################################ VIRTUAL MEMORY ###############################

### WARNING! Virtual Memory is deprecated in Redis 2.4
### The use of Virtual Memory is strongly discouraged.

### WARNING! Virtual Memory is deprecated in Redis 2.4
### The use of Virtual Memory is strongly discouraged.

# Virtual Memory allows Redis to work with datasets bigger than the actual
# amount of RAM needed to hold the whole dataset in memory.
# In order to do so very used keys are taken in memory while the other keys
# are swapped into a swap file, similarly to what operating systems do
# with memory pages.
# 指定是否启用虚拟内存机制，默认值为no，
# VM机制将数据分页存放，由Redis将访问量较少的页即冷数据swap到磁盘上，访问多的页面由磁盘自动换出到内存中
# 把vm-enabled设置为yes，根据需要设置好接下来的三个VM参数，就可以启动VM了
# vm-enabled no
# vm-enabled yes

# This is the path of the Redis swap file. As you can guess, swap files
# can't be shared by different Redis instances, so make sure to use a swap
# file for every redis process you are running. Redis will complain if the
# swap file is already in use.
#
# Redis交换文件最好的存储是SSD（固态硬盘）
# 虚拟内存文件路径，默认值为/tmp/redis.swap，不可多个Redis实例共享
# *** WARNING *** if you are using a shared hosting the default of putting
# the swap file under /tmp is not secure. Create a dir with access granted
# only to Redis user and configure Redis to create the swap file there.
# vm-swap-file /tmp/redis.swap

# With vm-max-memory 0 the system will swap everything it can. Not a good
# default, just specify the max amount of RAM you can in bytes, but it's
# better to leave some margin. For instance specify an amount of RAM
# that's more or less between 60 and 80% of your free RAM.
# 将所有大于vm-max-memory的数据存入虚拟内存，无论vm-max-memory设置多少，所有索引数据都是内存存储的（Redis的索引数据就是keys）
# 也就是说当vm-max-memory设置为0的时候，其实是所有value都存在于磁盘。默认值为0
# vm-max-memory 0

# Redis swap文件分成了很多的page，一个对象可以保存在多个page上面，但一个page上不能被多个对象共享，vm-page-size是要根据存储的数据大小来设定的。
# 建议如果存储很多小对象，page大小最后设置为32或64bytes；如果存储很大的对象，则可以使用更大的page，如果不确定，就使用默认值
# vm-page-size 32

# 设置swap文件中的page数量由于页表（一种表示页面空闲或使用的bitmap）是存放在内存中的，在磁盘上每8个pages将消耗1byte的内存
# swap空间总容量为 vm-page-size * vm-pages
#
# With the default of 32-bytes memory pages and 134217728 pages Redis will
# use a 4 GB swap file, that will use 16 MB of RAM for the page table.
#
# It's better to use the smallest acceptable value for your application,
# but the default is large in order to work in most conditions.
# vm-pages 134217728

# Max number of VM I/O threads running at the same time.
# This threads are used to read/write data from/to swap file, since they
# also encode and decode objects from disk to memory or the reverse, a bigger
# number of threads can help with big objects even if they can't help with
# I/O itself as the physical device may not be able to couple with many
# reads/writes operations at the same time.
# 设置访问swap文件的I/O线程数，最后不要超过机器的核数，如果设置为0，那么所有对swap文件的操作都是串行的，可能会造成比较长时间的延迟，默认值为4
# vm-max-threads 4

############################### ADVANCED CONFIG ###############################

# Hashes are encoded in a special way (much more memory efficient) when they
# have at max a given numer of elements, and the biggest element does not
# exceed a given threshold. You can configure this limits with the following
# configuration directives.
# 指定在超过一定的数量或者最大的元素超过某一临界值时，采用一种特殊的哈希算法
# hash-max-zipmap-entries 512
# hash-max-zipmap-value 64

# Similarly to hashes, small lists are also encoded in a special way in order
# to save a lot of space. The special representation is only used when
# you are under the following limits:
list-max-ziplist-entries 512
list-max-ziplist-value 64

# Sets have a special encoding in just one case: when a set is composed
# of just strings that happens to be integers in radix 10 in the range
# of 64 bit signed integers.
# The following configuration setting sets the limit in the size of the
# set in order to use this special memory saving encoding.
set-max-intset-entries 512

# Similarly to hashes and lists, sorted sets are also specially encoded in
# order to save a lot of space. This encoding is only used when the length and
# elements of a sorted set are below the following limits:
zset-max-ziplist-entries 128
zset-max-ziplist-value 64

# 指定是否激活重置哈希，默认为开启
activerehashing yes

################################## INCLUDES ###################################

# 指定包含其他的配置文件，可以在同一主机上多个Redis实例之间使用同一份配置文件，而同时各实例又拥有自己的特定配置文件
# include /path/to/local.conf
# include /path/to/other.conf

四、后端Java

后端项目中数据库ip地址位置填写yml文件中定义的服务名，它会自动设置为yml文件分配的ip，如图

docker-compose内后端服务

myweb:
    image: web/test1     # 镜像名
    build: .        # 表示以当前目录下的Dockerfile开始构建镜像
    ports:
      - "8090:8090"
    depends_on:
      - mysql
      - redis
    networks:
      data_security:
        ipv4_address: 10.1.0.4

通过depends_on来定义服务之间的依赖关系，会依据依赖关系启动服务，后端服务要在数据库mysql、redis启动之后启动服务

FROM java:8
#暴露的端口
EXPOSE 8090

#把打成的jar包更名为 app.jar
ADD *.jar app.jar

#在创建app.jar
RUN bash -c 'touch /app.jar'

#执行的运行jar包命令
ENTRYPOINT ["java", "-jar", "/app.jar"]

这里如果重新修改了后端项目中数据库的ip，且已经创建了后端镜像，请先删除已经创建了的后端镜像（我这里是myweb），不然数据库的ip地址是不会更新的。

五、容器间通信

Docker容器间通信是很常见的操作，它允许一个容器使用另一个容器提供的服务。

一般在使用docker-compose启动服务时，被同一个docker-compose.yml定于的服务（容器）会运行在一个隔离环境中，也就是说在这个环境中的容器是不能直接访问（如果没有设置的话）

networks:
  data_security:      # 自定义网络名字
    driver: bridge
    ipam:
      config:
        - subnet: 10.1.0.0/24       #自定义固定容器ip 实现容器间通讯，增强docker-compose项目可移植性

数据库和springboot项目分别使用不同的docker容器启动，这样会导致项目访问数据库受限，这里将docker-compose内所有服务都设置在同一网段中，可以管理容器及通信问题。 （在其他服务中不要设置IP地址为x.x.x.1，容易报错）

可以进入创建的docker网络查看一下相关信息

docker network ls		        # 输出docker网络列表
docker network inspect 网络id		# 查看指定网络详情
docker network rm 网络id		# 删除指定网络

六、完整代码

docker-compose.yml

在docker-compose.yml文件目录下直接输入第一条命令启动服务

docker-compose up			# 开启服务并显示日志
docker-compose up -d		        # 后台开启服务
docker logs -f 容器id		        # 查看指定已开启容器日志
docker-compose down			# 一键关闭所有服务并清除已退出的容器

七、运行截图

如图，服务启动正常，浏览器输入http://your-ip:8080查看效果，没有效果的查看一下防火墙是否关了。
