docker images

查看本地镜像

docker ps

查看运行中的docker容器
docker ps -a 查看所有容器，包括退出的。

查看某镜像启动日志

docker logs 镜像id

docker search tomcat

从镜像仓库搜索镜像

pull镜像

docker pull tomcat

启动/关闭/重启容器

docker start/stop/restart 容器id

运行容器-tomcat

docker run -d -p 8080:8080 tomcat
-d: 后台启动
-p: 端口映射
-P: 随机端口映射。docker run -d -P tomcat

进入容器

docker run -d -p 8080:8080 tomcat => 启动tomcat容器后，并没有进入容器。

docker attach 容器id => 退出后会关闭容器(不推荐)
docker exec -it 容器id bash
-i: interactive 交互的
-t: terminal 伪终端
bash: 这个参数必须带，或者写成/bin/bash也行

退出容器

exit

删除容器

docker rm 容器id1 容器id2
如果容器运行中，可以加-f强制删除：force

docker容器中没有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

本地复制文件到docker容器内

docker cp xxx containerId:/usr/share/elasticsearch/plugins

docker容器内复制文件到本地

docker cp containerId:/usr/share/elasticsearch/plugins/a.txt /root

elasticsearch踩坑

给/usr/share/elasticsearch/plugins下复制了一个ik分词器文件进去，然后elasticsearch容器重启失败，而不进入容器又不能做文件删除(但可以从里边cp文件到本地)。
docker貌似不提供：在不启动容器的情况下对容器内文件的删除操作。
于是本地全局搜索：find / -name xxx => 删除文件后elasticsearch正常启动。

ik分词器

ik分词器的版本号要跟es完全一致[小版本号也要一致]
如果找不到对应版本号的ik分词器，可以修改plugin-descriptor.properties的版本号，这样能够正常启动es。

对于ik分词器建议是索引时使用ik_max_word将搜索内容进行细粒度分词，搜索时使用ik_smart提高搜索精确性

输入：
{
  "analyzer": "ik_max_word",    -- 最多分词数量
  "text": "我是中国人"
}

输出：
{
    "tokens": [
        {
            "token": "我",
            "start_offset": 0,
            "end_offset": 1,
            "type": "CN_CHAR",
            "position": 0
        },
        {
            "token": "是",
            "start_offset": 1,
            "end_offset": 2,
            "type": "CN_CHAR",
            "position": 1
        },
        {
            "token": "中国人",
            "start_offset": 2,
            "end_offset": 5,
            "type": "CN_WORD",
            "position": 2
        },
        {
            "token": "中国",
            "start_offset": 2,
            "end_offset": 4,
            "type": "CN_WORD",
            "position": 3
        },
        {
            "token": "国人",
            "start_offset": 3,
            "end_offset": 5,
            "type": "CN_WORD",
            "position": 4
        }
    ]
}

======================

输入：
{
  "analyzer": "ik_smart",   -- 聪明的分词(比较精准，比较少)
  "text": "我是中国人"
}
输出：
{
    "tokens": [
        {
            "token": "我",
            "start_offset": 0,
            "end_offset": 1,
            "type": "CN_CHAR",
            "position": 0
        },
        {
            "token": "是",
            "start_offset": 1,
            "end_offset": 2,
            "type": "CN_CHAR",
            "position": 1
        },
        {
            "token": "中国人",
            "start_offset": 2,
            "end_offset": 5,
            "type": "CN_WORD",
            "position": 2
        }
    ]
}

docker启动MySQL

docker exec -it id bash
bash-4.2$ mysql -h 127.0.0.1 -u root
