TL; DR - Ubuntu 14.04上的Dockerized Ambari Docker容器在默认配置启动时抛出错误
我试图将Ambari部署Dockerize以支持在我的Hadoop容器旁边运行它。这是我的Dockerfile:
FROM ubuntu:14.04

ENV AMBARI_VERSION 2.2.0.0

#Disable SELinux
RUN echo SELINUX=disabled >> /etc/selinux/config
EXPOSE 8080
RUN ambari-server setup -s --verbose --java-home $JAVA_HOME
CMD ambari-server start
当我启动容器时,我收到以下错误 -
Using python /usr/bin/python2

REASON: Ambari Server java process died with exitcode -1. Check /var/log/ambari-server/ambari-server.out for more information.
在ambari-server.log或.out
中似乎没什么用处。我发现WARNING: setpgid(73, 0) failed - [Errno 13] Permission denied
修复了此问题:setpgid issue
从阅读用于部署到Ubuntu 14.04的HortonWorks文档,这应该有效:
Install Ambari on Ubuntu 14.04
我尝试使用嵌入式Postges以及具有相同结果的外部Postges进行部署。
一个有趣的注意事项是,即使出现错误,Ambari似乎已经启动,我可以登录为默认的admin / admin,但是在调用`ambari-server stop'它说没有进程正在运行......
root@3e6d778b43f8:/opt/ambari# ambari-server stop
Using python /usr/bin/python2
Stopping ambari-server
Ambari Server is not running
root@3e6d778b43f8:/opt/ambari# jps
868 AmbariServer
955 Jps
我明天会在我的Ubuntu盒子上复制这个设置,看看是否会发生同样的事情。
谢谢!

我在ubuntu 14.04上的docker中遇到了与ambari-server相同的问题。你能尝试下面的
吗?在/ etc / default / docker中添加
DOCKER_OPTS="--storage-driver=devicemapper"
并重新启动docker服务。请注意,在此之后,所有图像都将消失(http://muehe.org/posts/switching-docker-from-aufs-to-devicemapper/)。重建你的图像。
说实话,我并不是100%确定这部分是否真的需要。
从aufs切换到devicemapper后,您可能会收到以下错误:
ERROR: Could not find container for entity id
解决方案是删除旧的AUFS数据库和任何现有容器:
sudo rm -rf /var/lib/docker/containers/*
sudo rm -rf /var/lib/docker/linkgraph.db
重新启动docker镜像/容器现在应该可以在devicemapper引擎上运行。
在/etc/apparmor.d/docker
内注释(#)行deny @{PROC}/{*,**^[0-9*],sys/kernel/shm*} wkx,
,它会以某种方式混淆apparmor utils。比跑
sudo aa-complain /etc/apparmor.d/docker
如果aa-complain throws命令未找到,请安装:
sudo apt-get install apparmor-utils
启动容器后,ambari-server开始为我工作。
我不知道docker如何依赖于apparmor,即上述操作带来的风险......

将Ambari部署到docker容器似乎存在问题。我将其分解并将其安装到具有以下脚本的Vagrant 14.04 Ubuntu VM上:
<强> install_java.sh 强>
#!/bin/bash
echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | debconf-set-selections && \
add-apt-repository -y ppa:webupd8team/java && \
apt-get update && \
apt-get install -y oracle-java8-installer && \
rm -rf /var/lib/apt/lists/* && \
rm -rf /var/cache/oracle-jdk8-installer
<强> install_ambari.sh 强>
#!/bin/bash
export DEBIAN_FRONTEND=noninteractive \
&& wget -nv http://public-repo-1.hortonworks.com/ambari/ubuntu14/2.x/updates/2.2.0.0/ambari.list -O /etc/apt/sources.list.d/ambari.list \
&& apt-key adv --recv-keys --keyserver keyserver.ubuntu.com B9733A7A07513CAD \
&& apt-get update \
&& apt-get -y install ambari-server
其次是:
sudo ambari-server setup -s -v -j $JAVA_HOME
sudo ambari-server start -v
@thaJeztah - 我的Dockerfile设置需要修复什么?
