Question

我是新的Codenvy用户。我试图在Codenvy建立一个“堆栈”，它将运行postgres。

我正在使用以下配方创建我的堆栈。（使用https://github.com/eclipse/che-dockerfiles/blob/master/recipes/ubuntu_jdk8/Dockerfile作为起点）

此配方创建一个包含Eclipse Che，Maven和Tomcat的Codenvy服务器。

我需要将Ant和Postgres添加到此配置中。我能够添加Ant。我目前面临的挑战是将Postgres添加到此配置中。

这是我目前的食谱。

FROM eclipse/stack-base:ubuntu

    rm -rf /home/user/tomcat8/webapps/* && \
    echo "export MAVEN_OPTS=\$JAVA_OPTS" >> /home/user/.bashrc

我找到了一个使用以下命令安装postgres的示例dockerfile

RUN apt-get update && apt-get install -y ant git postgresql-client postgresql-contrib

当我将此添加到我的Codenvy Stack配方中时，我在尝试启动工作区时看到失败。

[DOCKER] Step 13/13 : RUN apt-get update && apt-get install -y ant git postgresql-client postgresql-contrib
[DOCKER] ---> Running in 672fc2aac027

[DOCKER] 
[DOCKER] [ERROR] Failed to build image: The command '/bin/sh -c apt-get update && apt-get install -y ant git postgresql-client postgresql-contrib' returned a non-zero code: 100

在此环境中安装postgres的正确方法是什么？安装完成后，如何确保postgres服务已启动？

Answer 1

Docker的主要好处之一不是重新发明轮子。您应该使用官方PostgreSQL image。

如果基础PostgreSQL图像不足以满足您的需求，请继承它并在顶部添加您需要的任何内容。

作为一般规则，如果您要在#!/bin/sh MONITORDIR="/path/to/directory" inotifywait -m -r -e create --format '%w%f' "${MONITORDIR}" | while read NEWFILE do [ -z "${NEWFILE}" ] && : || MOVIE=$(find "$NEWFILE" -type f -not -name ".*" $ -iname "*.mkv" -o -iname "*.mp4" -o -iname "*.avi" $ -exec basename {} \; | sed 's/\.[^.]*$//') [ -z "${MOVIE}" ] && : || echo "Please don't reply to this automatically generated email message." | mail -s "$MOVIE is now on Plex!" "email1@gmail.com,email2@gmail.com" done之外构建图像，请三思而后行，因为您可能使用了错误的工具来完成工作。

我在GitHub的codenvy repo的帮助下解决了这个问题。
