Docker容器大行其道,直接通過 docker pull + 啟動參數的方式運行比較麻煩, 可以通過docker-compose插件快速創建容器
1.安裝docker-compose
- 安裝
curl -L "https://github.com/docker/compose/releases/download/1.23.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
-
添加權限
chmod +x /usr/local/bin/docker-compose -
查看
$ docker-compose --version
docker-compose version 1.23.1, build 1719ceb
- 刪除
rm /usr/local/bin/docker-compose
2.創建docker-compose.yml
version: ‘3.1‘ services: zoo1: image: zookeeper restart: always hostname: zoo1 ports: - 2181:2181 environment: ZOO_MY_ID: 1 ZOO_SERVERS: server.1=zoo1:2888:3888
3.執行自動安裝部署
docker-compose up -d
使用-d後臺運行容器
[root@localhost zook]# systemctl start firewalld.service
[root@localhost zook]# docker-compose up -d
Creating network "zook_default" with the default driver
Creating zook_zoo1_1_5803e136833d ... done
4.連接容器
[root@localhost zook]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3efbee2be660 zookeeper "/docker-entrypoint.…" 2 minutes ago Up 2 minutes 2888/tcp, 0.0.0.0:2181->2181/tcp, 3888/tcp zook_zoo1_1_bad722f020ce [root@localhost zook]# docker exec -it 3efbee2be660 /bin/bash
5.啟動zookeeper服務
bash-4.4# ./bin/zkCli.sh -server 127.0.0.1:2181
Connecting to 127.0.0.1:2181
2018-12-09 16:10:10,644 [myid:] - INFO [main:Environment@100] - Client environment:zookeeper.version=3.4.13-2d71af4dbe22557fda74f9a9b4309b15a7487f03, built on 06/29/2018 04:05 GMT
2018-12-09 16:10:10,649 [myid:] - INFO [main:Environment@100] - Client environment:host.name=zoo1
...
2018-12-09 16:10:10,859 [myid:] - INFO [main-SendThread(localhost:2181):ClientCnxn$SendThread@879] - Socket connection established to localhost/127.0.0.1:2181, initiating session
[zk: 127.0.0.1:2181(CONNECTING) 0] 2018-12-09 16:10:10,922 [myid:] - INFO [main-SendThread(localhost:2181):ClientCnxn$SendThread@1303] - Session establishment complete on server localhost/127.0.0.1:2181, sessionid = 0x100018a493b0000, negotiated timeout = 30000
6.客戶端驗證
bash-4.4# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /conf/zoo.cfg
Mode: standalone
docker-compose up會優先使用已有的容器，而不是重新創建容器。
下面的方法可以解決你的問題：
docker-compose up -d --force-recreate
使用 --force-recreate 可以強制重建容器,否則只能在容器配置有更改時才會重建容器
docker-compose down
停止所有容器，並刪除容器,下次使用docker-compose up時就一定會是新容器了
