docker的一些总结

操作系统基础镜像

名称	大小	包管理	场景
busybox	1.xMB	apk, lbu	超级简化版嵌入式
alpine	5.x MB	apk, lbu	Alpine是一个面向安全的、轻量级的Linux系统，基于musl libc和busybox
ubuntu	70~80 MB	apt-get, dpkg	非常出色的Linux发行版
debian	120~+/- MB	apt-get, dpkg	非常出色的Linux发行版,很多基于它的发行版
centos	200+ MB	yum, rpm	CentOS是RedHat的社区版

编程语言基础镜像

名称	tag	说明
java	openjdk:11	由于oracle jdk版本，不提供docker官方,可手动下载打docker镜像
python	3.9.7-alpine3.14	略
go	1.16.8-alpine3.14	略
nodejs	14-alpine3.12/16-alpine3.12	略

alpine/git	临时的git command	A simple git container running in alpine linux, especially for tiny linux distro.
alpine/helm	heam相关	Auto-trigger docker build for kubernetes helm when new release is announced
alpine/jmeter	压测	略
alpine/dfimage	解析镜像中的内容，便于重新反写Dockerfile文件	reverse Docker images into Dockerfiles

运行一些常用docker的命令

mysql server :

1	docker run --name mysql8 -v /data/mysql8/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:8.0.26 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci

redis:

1	run -d --name redis -p 6379:6379 -v /mnt/redis/data:/data -v /mnt/redis/conf/redis.conf:/etc/redis/redis.conf redis:4 --requirepass "redispass"

portainer:

1	docker run -d -p 8000:8000 -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer

elasticsearch:

1	docker run --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms512m -Xmx768m" -d elasticsearch:7.12.0

运行一个操作系统或某种环境，在后台：

1	docker run -d centos /bin/bash -c "while true;do echo hello ;sleep 3;done"

jenkins:

1 2	docker run --name myjenkins -p 8080:8080 -p 50000:50000 -v /var/jenkins_home jenkins

git:

1	docker run -ti --rm -v ${HOME}:/root -v $(pwd):/git alpine/git clone https://github.com/alpine-docker/git.git

dfimage:

1
2

alias dfimage="docker run -v /var/run/docker.sock:/var/run/docker.sock --rm alpine/dfimage"
dfimage -sV=1.36 nginx:latest # (It will pull the target docker image automaticlaly. Parameter -sV=1.36 is not always required.)

ansible:

alias ansible="docker run -ti --rm -v ~/.ssh:/root/.ssh -v ~/.aws:/root/.aws -v $(pwd):/apps -w /apps alpine/ansible ansible"
ansible <follow command>
或
alias ansible-playbook=" docker run -ti --rm -v ~/.ssh:/root/.ssh -v ~/.aws:/root/.aws -v $(pwd):/apps -w /apps alpine/ansible ansible-playbook"
ansible-playbook -i inventory < follow command>

几个Dockerfile

mysql client

FROM alpine:latest
RUN echo https://mirrors.aliyun.com/alpine/latest-stable/main/ > /etc/apk/repositories
RUN apk add --no-cache mysql-client

jdk 17(这里如果使用alpine的话，有报错，因此采用ubuntu镜像):

FROM ubuntu:20.04
ADD jdk-17_linux-x64_bin.tar.gz /root
ENV JAVA_HOME /root/jdk-17/
ENV PATH $PATH:$JAVA_HOME/bin
ENTRYPOINT ["java", "-version"]

go:

FROM golang:1.17

WORKDIR /go/src/app
COPY . .

RUN go get -d -v ./...
RUN go install -v ./...

CMD ["app"]

Yearning:

FROM alpine:3.12

LABEL maintainer="HenryYee-2020/11/16"

EXPOSE 8000

COPY Yearning  /opt/Yearning
COPY conf.toml /opt/conf.toml

RUN echo "http://mirrors.ustc.edu.cn/alpine/v3.12/main/" > /etc/apk/repositories && \
      apk add --no-cache tzdata libc6-compat && \
      ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
      echo "Asia/Shanghai" >> /etc/timezone && \
      echo 'hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4' >> /etc/nsswitch.conf

WORKDIR /opt

CMD /opt/Yearning install && /opt/Yearning run
