在ECS上利用 docker 部署 jar 包时出现如下错误：
redis.clients.jedis.HostAndPort - cant resolve localhost address
是因为spring-redis在初始化时会实例化LocalHost，但是ECS的host name并没有在设置，解决方案是在 /etc/hosts 中设置ECS的host name。
比如：ssh 登录后，界面显示 user@abcdefg ，则在 /etc/hosts 中添加 127.0.0.1 abcdefg 。
1、准备好 docker 环境。
2、拉取镜像：
docker pull portainer/portainer
3、运行实例：
# 单机（本机）
docker run -d --name portainer -p 9000:9000 -v "/var/run/docker.sock:/var/run/docker.sock" portainer/portainer
# 群集
docker run -d --name portainer -p 9000:9000 portainer/portainer
4、添加 docker registries
名称：microsoft
地址：dockerhub.azk8s.cn
docker pull jenkins/jenkins
docker run -p 8080:8080 -p 50000:50000 -v /home/jenkins_home:/var/jenkins_home jenkins/jenkins
首次安装时要求输入安装密钥，需要首先进入 docker 容器内，再查看对应的文件。
docker exec -it jenkins bash
-v /etc/localtime:/etc/localtime:ro
或
-e "TZ=Asia/Shanghai"
ENV TZ=America/Los_Angeles
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
Docker 的安装资源文件存放在Amazon S3，国内下载速度极其缓慢。您可以通过执行下面的命令，使用镜像站点，高速安装Docker。
# 阿里云
curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
# DaoCloud镜像
curl -sSL https://get.daocloud.io/docker | sh
docker pull sath89/oracle-xe-11g
docker run -d --restart always -p 8080:8080 -p 1521:1521 -v /etc/localtime:/etc/localtime:ro -v /my/oracle/data:/u01/app/oracle sath89/oracle-xe-11g

Convert these .rpm files into .deb packages and install using "alien" ("sudo apt-get install alien" if you don’t have it).
For example, for version 12.1.0.2.0-1 for Linux x86_64 (64-bit):
alien -i oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm
alien -i oracle-instantclient12.1-sqlplus-12.1.0.2.0-1.x86_64.rpm
alien -i oracle-instantclient12.1-devel-12.1.0.2.0-1.x86_64.rpm
sqlplus system/oracle@//localhost:1521/xe
If you execute sqlplus and get "sqlplus: command not found", see the section below about adding the ORACLE_HOME variable.
If sqlplus complains of a missing libsqlplus.so file, follow the steps in the section "Integrate Oracle Libraries" below.
If sqlplus complains of a missing libaio.so.1 file, run
sudo apt-get install libaio1
or, if you’re installing the 32 bit instant client on 64 bit,
sudo apt-get install libaio1:i386
If oracle applications, such as sqlplus, are complaining about missing libraries, you can add it to the system library list create a new file as follows:
sudo vi /etc/ld.so.conf.d/oracle.conf && sudo chmod o+r /etc/ld.so.conf.d/oracle.conf
and add the oracle library path as the first line. For example,
/usr/lib/oracle/12.1/client64/lib/
Then run ldconfig:
sudo ldconfig
Many Oracle database applications look for Oracle software in the location specified in the environment variable ‘ORACLE_HOME’.
Typical workstations will only have one Oracle install, and will want to define this variable in a system-wide location.
sudo vi /etc/profile.d/oracle.sh && sudo chmod o+r /etc/profile.d/oracle.sh
Add the following:
export ORACLE_HOME=/usr/lib/oracle/12.1/client64
Alternatively, each user can define this in their ~/.bash_profile
Note: From Ubuntu 11.04 (confirmed in 11.04 and 14.04) sqlplus was not recognized as a command unless the following line was also included in the oracle.sh file:
export PATH=$PATH:$ORACLE_HOME/bin
