注意：只有在使用 Compose 文件格式的版本2或更高版本時，本文才適用。網(wǎng)絡功能不支持版本1（傳統(tǒng)）撰寫文件。
默認情況下，組合設置一個網(wǎng)絡你的應用程序。服務的每個容器都加入了默認網(wǎng)絡，并且兩者都是?？蛇_網(wǎng)絡上的其他容器，以及可發(fā)現(xiàn)由它們在主機名上與容器名稱相同。
注：您的應用程序的網(wǎng)絡是根據(jù)“項目名稱”命名的，該名稱基于它所在的目錄的名稱?？梢允褂?code>--project-name標志或者
COMPOSE_PROJECT_NAME環(huán)境變量。
例如，假設應用程序位于一個名為myapp，而你的docker-compose.yml看起來是這樣的：
version: "3"services: web: build: . ports: - "8000:8000" db: image: postgres ports: - "8001:5432"
當運行docker-compose up的時候，發(fā)生如下情況：
myapp_default被創(chuàng)造了。
容器是使用
web的配置。它加入了網(wǎng)絡myapp_default以這個名字web。
容器是使用
db的配置。它加入了網(wǎng)絡myapp_default以這個名字db。
每個容器現(xiàn)在都可以查找主機名。web或db并獲取適當容器的
IP 地址。例如，web的應用程序代碼可以連接到
URL postgres://db:5432然后開始使用 Postgres 數(shù)據(jù)庫。
注意區(qū)分HOST_PORT和區(qū)分是重要的CONTAINER_PORT。在上面的例子中，db中，HOST_PORT是8001和容器端口是5432（postgres的默認值）。網(wǎng)絡服務對服務通信使用CONTAINER_PORT。何時HOST_PORT被定義，該服務也可以在群外訪問。
在web容器，連接字符串到db看起來就像postgres://db:5432，從主機上看，連接字符串看起來像postgres://{DOCKER_IP}:8001...
更新容器
如果對服務進行配置更改并運行docker-compose up要更新它，舊容器將被刪除，新容器將以不同的 IP 地址加入網(wǎng)絡，但名稱相同。正在運行的容器將能夠查找該名稱并連接到新地址，但舊地址將停止工作。
如果任何容器與舊容器有連接，則它們將被關閉。容器的責任是檢測此狀態(tài)，再次查找名稱并重新連接。
鏈接
鏈接允許您定義額外的別名，通過它可以從另一個服務訪問服務。他們不需要啟用服務進行通信 - 默認情況下，任何服務都可以以該服務的名稱到達任何其他服務。在以下示例中，db可以從web主機名db和以下位置訪問database：
version: "3"services: web: build: . links: - "db:database" db: image: postgres
見鏈接參考想了解更多信息。
多主機聯(lián)網(wǎng)
注意：本節(jié)中的指示信息涉及傳統(tǒng)的 Docker Swarm 操作，并且僅在針對傳統(tǒng) Swarm 集群時才起作用。有關將撰寫項目部署到較新的集成群模式的說明，請參閱 Docker Stacks 文檔。
何時將組合應用程序部署到群集集群，您可以使用內置的overlay驅動程序，以啟用容器之間的多主機通信，而不更改組合文件或應用程序代碼。
請參閱多主機網(wǎng)絡入門以了解如何設置 Swarm 群集。群集將overlay默認使用該驅動程序，但如果您愿意，您可以明確指定它 - 請參閱下文了解如何執(zhí)行此操作。
指定自定義網(wǎng)絡
您可以使用頂級networks密鑰指定您自己的網(wǎng)絡，而不只是使用默認的應用程序網(wǎng)絡。這使您可以創(chuàng)建更復雜的拓撲并指定自定義網(wǎng)絡驅動程序和選項。您還可以使用它將服務連接到不受
Compose 管理的外部創(chuàng)建的網(wǎng)絡。
每項服務都可以使用服務級別 networks密鑰來指定要連接的網(wǎng)絡，服務級別密鑰是頂級 networks密鑰下引用條目的名稱列表。
以下是定義兩個自定義網(wǎng)絡的示例撰寫文件。proxy服務與服務是隔離的db，因為它們不共享共享的網(wǎng)絡 - app只能與兩者通話。
version: "3"services: proxy: build: ./proxy networks: - frontend app: build: ./app networks: - frontend - backend db: image: postgres networks: - backend networks: frontend: # Use a custom driver driver: custom-driver-1 backend: # Use a custom driver which takes special options driver: custom-driver-2 driver_opts: foo: "1" bar: "2"
可以通過為每個連接的網(wǎng)絡設置 ipv4_address 和/或 ipv6_address 來為網(wǎng)絡配置靜態(tài) IP 地址。
有關可用網(wǎng)絡配置選項的詳細信息，請參閱下列參考資料：
頂層
networks鍵
服務級
networks鍵
配置默認網(wǎng)絡
除了指定您自己的網(wǎng)絡外，您還可以通過在networks名稱下定義條目來更改應用程序范圍的默認網(wǎng)絡的設置default：
version: "3"services: web: build: . ports: - "8000:8000" db: image: postgres networks: default: # Use a custom driver driver: custom-driver-1
使用預先存在的網(wǎng)絡
如果希望容器加入現(xiàn)有網(wǎng)絡，請使用external期權*
networks: default: external: name: my-pre-existing-network
而不是試圖創(chuàng)建一個名為[projectname]_default，將尋找一個名為my-pre-existing-network并將應用程序的容器連接到它。
