查看本地鏡像
docker ps
查看運行中的docker容器
docker ps -a 查看所有容器诗充，包括退出的。
查看某鏡像啟動日志
docker logs 鏡像id
docker search tomcat
從鏡像倉庫搜索鏡像
pull鏡像
docker pull tomcat
啟動/關(guān)閉/重啟容器
docker start/stop/restart 容器id
運行容器-tomcat
docker run -d -p 8080:8080 tomcat
-d: 后臺啟動
-p: 端口映射
-P: 隨機端口映射蝴蜓。docker run -d -P tomcat
進(jìn)入容器
docker run -d -p 8080:8080 tomcat => 啟動tomcat容器后，并沒有進(jìn)入容器茎匠。
- docker attach 容器id => 退出后會關(guān)閉容器(不推薦)
- docker exec -it 容器id bash
-i: interactive 交互的
-t: terminal 偽終端
bash: 這個參數(shù)必須帶诵冒，或者寫成/bin/bash也行
退出容器
exit
刪除容器
docker rm 容器id1 容器id2
如果容器運行中，可以加-f強制刪除：force
docker容器中沒有vi/vim等命令
apt-get update
apt-get install vim
容器重命名
docker rename 原容器名 新容器名
本地復(fù)制文件到docker容器內(nèi)
docker cp xxx containerId:/usr/share/elasticsearch/plugins
docker容器內(nèi)復(fù)制文件到本地
docker cp containerId:/usr/share/elasticsearch/plugins/a.txt /root
elasticsearch踩坑
給/usr/share/elasticsearch/plugins下復(fù)制了一個ik分詞器文件進(jìn)去汽馋，然后elasticsearch容器重啟失敗，而不進(jìn)入容器又不能做文件刪除(但可以從里邊cp文件到本地)悄雅。
docker貌似不提供：在不啟動容器的情況下對容器內(nèi)文件的刪除操作铁蹈。
于是本地全局搜索：find / -name xxx => 刪除文件后elasticsearch正常啟動。

ik分詞器
ik分詞器的版本號要跟es完全一致[小版本號也要一致]
如果找不到對應(yīng)版本號的ik分詞器，可以修改plugin-descriptor.properties的版本號娩梨，這樣能夠正常啟動es览徒。
對于ik分詞器建議是索引時使用ik_max_word將搜索內(nèi)容進(jìn)行細(xì)粒度分詞，搜索時使用ik_smart提高搜索精確性
輸入：
{
"analyzer": "ik_max_word", -- 最多分詞數(shù)量
"text": "我是中國人"
}
輸出：
{
"tokens": [
{
"token": "我",
"start_offset": 0,
"end_offset": 1,
"type": "CN_CHAR",
"position": 0
},
{
"token": "是",

"end_offset": 2,
"type": "CN_CHAR",
"position": 1

}
======================
輸入：
{
"analyzer": "ik_smart", -- 聰明的分詞(比較精準(zhǔn)掸冤，比較少)
"text": "我是中國人"
}
輸出：

docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 id
docker exec -it id bash
bash-4.2$ mysql -h 127.0.0.1 -u root
