DOS日期空格处理

set build_time="%date:~0,4%%date:~5,2%%date:~8,2%%time:~0,2%%time:~3,2%"
set build_time=%build_time: =0%

node的typescript的常用操作

1.安装node版本，建议选择v8.11.3版本。

https://nodejs.org/dist/v8.11.3/node-v8.11.3-x64.msi<pre>
2.安装visual studio code，选择最新版。
【npm的所有命令，请不要powershell中执行，目前还不知道为什么在本人环境发现在执行npm config set注册下载源时，会出错，且错得很离谱。故需要用cmd.exe来解决。】
3.安装全局组件。
  <pre lang="geshi">
     npm install -g typescript
     npm install -g pm2
     npm install -g ts-node

4.安装本地组件
npm install
5.如果觉得安装有问题，可以直接清理npm缓存及组件。
%appdata%/npm和%appdata%/npm

mongo分片及副本集搭建例子

https://github.com/senssei/mongo-cluster-docker

基于上面仓库，改造了一个副本集。
https://github.com/kxtry/mongo-cluster-docker

1.副本集docker-compose脚本

version: '3'
services:
    mgoprimary:
        container_name: "mgoprimary"
        image: mongo:4.2
        ports:
            - "27017:27017"
        command: mongod --replSet vmlocal --port 27017  --oplogSize 16
        links:
            - mgoreplica1:mgoreplica1
            - mgoreplica2:mgoreplica2
        restart: always
        extra_hosts:
            - "mgo.db.com:{{extern_ip}}"
        volumes:
            - /etc/localtime:/etc/localtime:ro
            - /etc/timezone:/etc/timezone:ro
            - ./data/mgoprimary/data:/data/db
 
    mgoreplica1:
        container_name: "mgoreplica1"
        image: mongo:4.2
        ports:
            - "27018:27017"
        command: mongod --replSet vmlocal --port 27017  --oplogSize 16
        restart: always
        extra_hosts:
            - "mgo.db.com:{{extern_ip}}" 
        volumes:
            - /etc/localtime:/etc/localtime:ro
            - /etc/timezone:/etc/timezone:ro
            - ./data/mgoreplica1/data:/data/db
 
    mgoreplica2:
        container_name: "mgoreplica2"
        image: mongo:4.2
        ports:
            - "27019:27017"
        command: mongod --replSet vmlocal --port 27017  --oplogSize 16        
        restart: always
        extra_hosts:

        volumes:
            - /etc/localtime:/etc/localtime:ro
            - /etc/timezone:/etc/timezone:ro
            - ./data/mgoreplica2/data:/data/db
 
    setup-vmlocal:
        container_name: "setup-vmlocal"
        image: mongo:4.2
        depends_on:
            - "mgoprimary"
            - "mgoreplica1"
            - "mgoreplica2"
        extra_hosts:
            - "mgo.db.com:{{extern_ip}}"
        links:

            - MONGO2=mgo.db.com:27018
            - MONGO3=mgo.db.com:27019
            - RS=vmlocal
        entrypoint: [ "/scripts/setup.sh" ]

version: '3' services: mgoprimary: container_name: "mgoprimary" image: mongo:4.2 ports: - "27017:27017" command: mongod --replSet vmlocal --port 27017 --oplogSize 16 links: - mgoreplica1:mgoreplica1 - mgoreplica2:mgoreplica2 restart: always extra_hosts: - "mgo.db.com:{{extern_ip}}" volumes: - /etc/localtime:/etc/localtime:ro - /etc/timezone:/etc/timezone:ro - ./data/mgoprimary/data:/data/db mgoreplica1: container_name: "mgoreplica1" image: mongo:4.2 ports: - "27018:27017" command: mongod --replSet vmlocal --port 27017 --oplogSize 16 restart: always extra_hosts: - "mgo.db.com:{{extern_ip}}" volumes: - /etc/localtime:/etc/localtime:ro - /etc/timezone:/etc/timezone:ro - ./data/mgoreplica1/data:/data/db mgoreplica2: container_name: "mgoreplica2" image: mongo:4.2 ports: - "27019:27017" command: mongod --replSet vmlocal --port 27017 --oplogSize 16 restart: always extra_hosts: - "mgo.db.com:{{extern_ip}}" volumes: - /etc/localtime:/etc/localtime:ro - /etc/timezone:/etc/timezone:ro - ./data/mgoreplica2/data:/data/db setup-vmlocal: container_name: "setup-vmlocal" image: mongo:4.2 depends_on: - "mgoprimary" - "mgoreplica1" - "mgoreplica2" extra_hosts: - "mgo.db.com:{{extern_ip}}" links: - mgoprimary:mgoprimary - mgoreplica1:mgoreplica1 - mgoreplica2:mgoreplica2 volumes: - ./scripts:/scripts environment: - MONGO1=mgo.db.com:27017 - MONGO2=mgo.db.com:27018 - MONGO3=mgo.db.com:27019 - RS=vmlocal entrypoint: [ "/scripts/setup.sh" ]

3.与docker-compose.yml相同子目录下的./scripts/setup.sh脚本

#!/bin/bash 
 
mongodb1="${MONGO1}"
mongodb2="${MONGO2}"
mongodb3="${MONGO3}"
 
echo "Waiting for startup.."
until mongo --host ${mongodb1} --eval 'quit(db.runCommand({ ping: 1 }).ok ? 0 : 2)' &>/dev/null; do
  printf '.'
  sleep 1
done
 
echo "Started.."
 
echo setup.sh time now: `date +"%T" `
mongo --host ${mongodb1} <<EOF
   var cfg = {
        "_id": "${RS}",
        "protocolVersion": 1,
        "members": [
            {
                "_id": 0,
                "host": "${mongodb1}"
            },
            {
                "_id": 1,
                "host": "${mongodb2}"
            },
            {
                "_id": 2,
                "host": "${mongodb3}"
            }
        ]
    };
    rs.initiate(cfg, { force: true });
    rs.reconfig(cfg, { force: true });
EOF

3.构建脚本build_cluster.sh

#!/bin/sh                                                                                                                                                                                                   
 
path_current=`pwd`                                                                                                                                                                                          
path_script=$(cd "$(dirname "$0")"; pwd)                                                                                                                                                                    
 
mode=$1

        if [ -f $path_script/docker-compose.yml ]; then

Dockerfile的CMD和ENTRYPOINT的关系

以下示范，表示该形式下的CMD与ENTRYPOINT的关系。
CMD相当于应用程序的参数，ENTRYPOINT相当于应用的main入口或主程序入口。

FROM centos 
CMD ["echo 'p222 in cmd'"]     #传递给ENTRYPOINT的参数项。
ENTRYPOINT ["echo"]     #应用入口，相当于程序的main函数

1.构建

docker build  -t test .
<pre>
2.执行以下指令执行默认的CMD命令。
<pre lang="geshi">
docker run test
输出结果：
echo 'p222 in cmd'

3.修改程序输入参数

docker run test abct123
输出结果：
abct123
