一些经常或不经常用到的镜像启动方法

docker根据ffmpeg镜像启动容器 docker 启动镜像_docker

设置容器的TZ另一种办法

参考: https://github.com/spujadas/elk-docker/blob/master/start.sh

## override default time zone (Etc/UTC) if TZ variable is set
if [ ! -z "$TZ" ]; then
  ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
fi

带ssh的centos

docker run -d -p 0.0.0.0:2222:22 tutum/centos6
docker run -d -p 0.0.0.0:2222:22 tutum/centos


docker run -d -p 0.0.0.0:2222:22 -v /etc/localtime:/etc/localtime:ro -v /etc/timezone:/etc/timezone:ro  tutum/centos6
docker run -d -p 0.0.0.0:2222:22 -v /etc/localtime:/etc/localtime:ro -v /etc/timezone:/etc/timezone:ro tutum/centos

支持两种验证方式:
docker run -d -p 0.0.0.0:2222:22  -v /etc/localtime:/etc/localtime:ro -v /etc/timezone:/etc/timezone:ro -e ROOT_PASS="mypass" tutum/centos
docker run -d -p 2222:22 -e AUTHORIZED_KEYS="`cat ~/.ssh/id_rsa.pub`" tutum/centos

docker logs <CONTAINER_ID>
ssh -p <port> root@<host>

参考: https://hub.docker.com/r/tutum/centos/

带ping/curl/nslookup的busybox

docker run -itd --name=test1 --net=test-network radial/busyboxplus /bin/sh

  docker run -d -e REPLICATION_SLAVE=true -p 3307:3306 --link mysql:mysql tutum/mysql

gogs安装(不过建议用gitlab)

docker run -itd \
    -p 53000:3000 -p 50022:22 \
    -v /data/gogs:/data  \
    -v /etc/localtime:/etc/localtime \
    --restart=always \
    gogs/gogs

cowcloud

docker run -v /data/owncloud-data:/var/www/html -v /etc/localtime:/etc/localtime -v :/var/www/html/config --restart=always -itd -p 8000:80 owncloud

nextcloud(和owncloud一样,据说这个支持在线md记录笔记,总之感觉功能更强大)

参考: https://hub.docker.com/_/nextcloud/

docker run -d \
-p 8080:80
-v nextcloud:/var/www/html \
nextcloud

安装confluence

docker run \
    -v /data/confluence/conflu_data:/var/atlassian/application-data/confluence \
    -v /etc/localtime:/etc/localtime \
    -v /data/confluence/server.xml:/opt/atlassian/confluence/conf/server.xml \

    --name="confluence" -d \
    -p 8090:8090 \
    -p 8091:8091 \
    cptactionhank/atlassian-confluence

参考:http://wuyijun.cn/shi-yong-dockerfang-shi-an-zhuang-he-yun-xing-confluence/

配置confluence

创建数据库

create database confluence default character set utf8 collate utf8_bin;
grant all on confluence.* to 'confluence'@"172.17.0.%" identified by "confluenceman";
grant all on confluence.* to 'confluence'@"192.168.6.%";
grant all on confluence.* to 'confluence'@"192.168.8.%";

安装破解

1.导出后用破机器破解
docker cp confluence:/opt/atlassian/confluence/confluence/WEB-INF/lib/atlassian-extras-decoder-v2-3.2.jar ./
mv atlassian-extras-decoder-v2-3.2.jar atlassian-extras-2.4.jar

2. 将破解文件导入系统
mv atlassian-extras-2.4.jar atlassian-extras-decoder-v2-3.2.jar
docker cp ./atlassian-extras-decoder-v2-3.2.jar  confluence:/opt/atlassian/confluence/confluence/WEB-INF/lib/

3.重启confluence
docker stop confluence
docker start confluence

1.贴上破机器的序列号
2.选jdbc连mysql url写:

jdbc:mysql://db:3306/confluence?sessionVariables=storage_engine%3DInnoDB&useUnicode=true&characterEncoding=utf8

3.导入既有的数据
参考:https://www.ilanni.com/?p=11989
如: xmlexport-20170902-100808-153.zip 这里包含了数据库数据.
4.安装完毕

管理员帐号密码登陆 http://192.168.x.x:8090
admin
xxxxx

5.配置邮箱
这里我没用server.xml里配置(配了测试有问题),直接smtp用新浪邮箱配的

smtp.sina.com
mt@sina.com
123456

phabricator审计系统(客服给开发提bug)

docker run -d \
    -p 9080:80 -p 9443:443 -p 9022:22 \
    --env PHABRICATOR_HOST=sj.pp100.net \
    --env MYSQL_HOST=192.168.x.x \
    --env MYSQL_USER=root \
    --env MYSQL_PASS=elc123 \
    --env PHABRICATOR_REPOSITORY_PATH=/repos \
    --env PHABRICATOR_HOST_KEYS_PATH=/hostkeys/persisted \
    -v /data/phabricator/hostkeys:/hostkeys \
    -v /data/phabricator/repo:/repos \
   redpointgames/phabricator

hackmarkdown安装(内网markdown服务器,支持贴图权限,还有专门的客户端等)

https://github.com/hackmdio/docker-hackmd/blob/master/docker-compose.yml

docker-compose up -d

参考: 数据的备份等都有.

容器启动常用选项

1, 时区
2, 自动重启
3, 日志

docker run \
-v /etc/localtime:/etc/localtime:ro
-v /etc/timezone:/etc/timezone:ro
--restart=always \

docker run \
-v /etc/localtime:/etc/localtime:ro
-v /etc/timezone:/etc/timezone:ro

-v /etc/localtime:/etc/localtime:ro -v /etc/timezone:/etc/timezone:ro

记录两份  一份是前台输出,另一份
docker run -it --rm -p 80:80 nginx
ll /var/lib/docker/containers/*/*.log

针对容器的日志切割(不然日志越滚越大)

容器日志目录: /var/lib/docker/containers//.log.*

docker run -d -v /var/lib/docker/containers:/var/lib/docker/containers:rw \
-v /etc/localtime:/etc/localtime:ro \
--restart=always \
tutum/logrotate

原理(logrotated的一个copytruncate选项很好,不截断日志情况下滚动日志)

## 可以进到容器里看看日志滚动策略.
#https://hub.docker.com/r/tutum/logrotate/

/ # cat /etc/logrotate.conf
/var/lib/docker/containers/*/*.log {
  rotate 0
  copytruncate
  sharedscripts
  maxsize 10M
  postrotate
    rm -f /var/lib/docker/containers/*/*.log.*
  endscript

#logrotate说明copytruncate
#    http://www.lightxue.com/how-logrotate-works

#让我联想起了nginx日志切割
cat > /etc/logrotate.d/nginx
/usr/local/nginx/logs/*.log {
    daily
    missingok
    rotate 7
    dateext
    compress
    delaycompress
    notifempty
    sharedscripts
    postrotate
        if [ -f /usr/local/nginx/logs/nginx.pid ]; then
            kill -USR1 `cat /usr/local/nginx/logs/nginx.pid`
        fi
    endscript
}

清理长时间不用的镜像和volumes

docker run -d \
  --privileged \
  -v /var/run:/var/run:rw \
  -v /var/lib/docker:/var/lib/docker:rw \
  -e IMAGE_CLEAN_INTERVAL=1 \
  -e IMAGE_CLEAN_DELAYED=1800 \
  -e VOLUME_CLEAN_INTERVAL=1800 \
  -e IMAGE_LOCKED="ubuntu:trusty, tutum/curl:trusty" \
  tutum/cleanup

#    https://hub.docker.com/r/tutum/cleanup/
#    IMAGE_CLEAN_INTERVAL   (optional) How long to wait between cleanup runs (in seconds), 1 by default.
#    IMAGE_CLEAN_DELAYED    (optional) How long to wait to consider an image unused (in seconds), 1800 by default.
#    VOLUME_CLEAN_INTERVAL  (optional) How long to wait to consider a volume unused (in seconds), 1800 by default.
#    IMAGE_LOCKED   (optional) A list of images that will not be cleaned by this container, separated by ,

原理:调用二进制程序

/ # cat run.sh
#!/bin/sh

if [ ! -e "/var/run/docker.sock" ]; then
    echo "=> Cannot find docker socket(/var/run/docker.sock), please check the command!"
    exit 1
fi

if [ "${IMAGE_LOCKED}" == "**None**" ]; then
    exec /cleanup \
        -imageCleanInterval ${IMAGE_CLEAN_INTERVAL} \
        -imageCleanDelayed ${IMAGE_CLEAN_DELAYED}
else
    exec /cleanup \
        -imageCleanInterval ${IMAGE_CLEAN_INTERVAL} \
        -imageCleanDelayed ${IMAGE_CLEAN_DELAYED} \
        -imageLocked "${IMAGE_LOCKED}"
fi

检查:

echo stat|nc127.0.0.1 2181

或者进入到容器去看
#docker exec zoo1 /zookeeper-3.4.10/bin/zkCli.sh  -server 127.0.0.1:2181
#/zookeeper-3.4.10/bin/zkCli.sh  -server 127.0.0.1:2181

修改es配置
0.0.0.0
http.cors.enabled: true
http.cors.allow-origin: "*"

修改内核:
vim /etc/security/limits.conf

sysctl -w vm.max_map_count=262144
sysctl -p

nohup /bin/su - elk -c "/usr/local/elasticsearch/bin/elasticsearch" > /data/es/es-start.log 2>&1 &
nohup /bin/su - elk -c "/usr/local/kibana/bin/kibana" > /data/es/kibana-start.log 2>&1 &

docker run -d -v /etc/localtime:/etc/localtime --restart=always -p 9100:9100 mobz/elasticsearch-head:5

安装elk的head插件

先修改es的配置文件: elasticsearch.yml追加
http.cors.enabled: true
http.cors.allow-origin: "*"


docker run -d -v /etc/localtime:/etc/localtime --restart=always -p 9100:9100 mobz/elasticsearch-head:5

物理机安装elk之前的优化操作
sudo sysctl -w vm.max_map_count=262144

make it persistent:
$ vim /etc/sysctl.conf
vm.max_map_count=262144

es常用操作参考:

启动jenkins

docker run -d -u root \
-p 8080:8080 \
-v /var/run/docker.sock:/var/run/docker.sock \
-v $(which docker):/bin/docker \
-v /var/jenkins_home:/var/jenkins_home \
jenkins

带ssh的tomcat

之前一直使用单个app的容器,如tomcat,我只需要catalina.sh run来启动前台容器.其中方法:我可以CMD ['run.sh'],其中run.sh有了我想执行的命令.
我也可以通过ENTRYPOINT ["docker-entrypoint.sh"],这样更加灵活了.可以通过CMD往这个脚本传参了.

后台tomcat容器需要ssh进去管理.这就意味着必须sshd也要同时前台启动,只能用supervisor来管理了.
但是我感觉还是不太完善.

1,熟悉dockerfile语法
2,手动构建centos7
3,使用官网centos7
4,系统层--基于官网cenos7 添加 supervisor+ssh,启动后即启动ssh
5,运行层—安装jdk
6,app层安装tomcat,暴露8080.—supervisor接管.

新总结下supervisord.conf的配置(tomcat+ssh镜像)
参考: https://github.com/zabbix/zabbix-docker/blob/3.4/web-apache-mysql/alpine/conf/etc/supervisor/conf.d/supervisord_zabbix.conf

[supervisord]
nodaemon = true


[program:sshd]
command=/usr/sbin/sshd -D
process_name=%(program_name)s
auto_start = true
autorestart = true

[program:tomcat]
command=/data/tomcat/bin/catalina.sh run
process_name=%(program_name)s
auto_start = true
autorestart = true


stdout_logfile = /dev/stdout
stdout_logfile_maxbytes = 0
stderr_logfile = /dev/stderr
stderr_logfile_maxbytes = 0

这是tomcat的dockerfile[tomcat+ssh镜像],
其中要准备,下载解压这些目录到Dockerfile所在目录, jdk, tomcat,tomcat的server.xml(后期我k8s集群使用cm来覆盖)

其中centos的dockerfile参考: https://github.com/tutumcloud/tutum-centos/blob/master/centos6/Dockerfile
这里可以指定ssh的密码,你也可以使用pwdgen(yum install)工具随机生成密码,打印在console口通过docker logs -f来查看到密码,后期直接自己改密码.参考那个github吧.

docker容器volume从容器里挂文件到宿主机

后来发现,-v选项之前是把容器外的数据挂容器里用刚想把容器里的某个文件挂到宿主机用,
只能挂出 run之后容器产生的数据,
如nginx: 可以获取到nginx的access日志和error日志,因为这些日志都是容器启动后生成的

docker run -itd -v /tmp/nginx/:/var/log/nginx/ -p 80:80 nginx

在比如centos: 我只在宿主机/tmp下发现hostname hosts resolv.conf这三个文件,这些文件是容器run之后产生的文件.

docker run -itd -v /tmp/etc/:/tmp/etc/ centos

nginx基于centos的dockerfile

参考: https://github.com/nginxinc/docker-nginx/blob/3ba04e37d8f9ed7709fd30bf4dc6c36554e578ac/mainline/stretch/Dockerfile
