如何将新软件包安装到非根Docker容器中？ [英] How to install new packages into non-root Docker Container?

问题描述

我正在尝试为SOLR扩展Docker容器。我只想在其中安装 vim 。但是当我运行docker build时，它抱怨我不是root用户。

I'm trying to extend a docker container for SOLR. I just want to install vim into it. But when I run the docker build it complains that I'm not root.

这是我要扩展的DockerFile：
https://github.com/makuk66/docker-solr/blob/master/5.3/Dockerfile

This is the DockerFile that I'm extending: https://github.com/makuk66/docker-solr/blob/master/5.3/Dockerfile

我的构建文件是这样的：

And my build file is this:

FROM makuk66/docker-solr
MAINTAINER OCSCommerce Team <[e-mail]>
RUN apt-get update
RUN apt-get --assume-yes install vim
COPY home/ocscommerce /etc/solr/home

然后输出以下内容：

192.168.99.100
localhost:solr$ docker build -t ocscommerce/solr .
Sending build context to Docker daemon 39.66 MB
Step 0 : FROM makuk66/docker-solr

Step 1 : MAINTAINER OCSCommerce Team <[e-mail]>

Step 2 : RUN apt-get update
 ---> Running in c865716a2694

E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

是否可以将软件包安装到此容器中？还是我需要从makuk66复制原始构建文件？

Is there any way to install a package into this container? Or would I need to copy the original build file from makuk66?

推荐答案

在 Dockerfile＃L24 ，用户已切换到 solr 。因此，如果将映像用作 FROM 的基本映像，则您自己的 Dockerfile 中的所有命令都由用户 solr

In the Dockerfile#L24, the user has been switched to solr. So if you use the image as base image with FROM, all commands in your own Dockerfile are running by the user solr

您可以通过从头开始构建Dockerfile来修复它。

You can fix it by building the Dockerfile from beginning.

FROM    java:openjdk-8-jre
MAINTAINER  Martijn Koster "[e-mail]"

ENV SOLR_VERSION 5.3.0
ENV SOLR solr-$SOLR_VERSION
ENV SOLR_USER solr

RUN export DEBIAN_FRONTEND=noninteractive && \
  apt-get update && \
  apt-get -y install lsof && \
  groupadd -r $SOLR_USER && \
  useradd -r -g $SOLR_USER $SOLR_USER && \
  mkdir -p /opt && \
  wget -nv --output-document=/opt/$SOLR.tgz http://www.us.apache.org/dist/lucene/solr/$SOLR_VERSION/$SOLR.tgz && \
  tar -C /opt --extract --file /opt/$SOLR.tgz && \
  rm /opt/$SOLR.tgz && \
  ln -s /opt/$SOLR /opt/solr && \
  mkdir -p /opt/solr/server/solr/lib && \
  chown -R $SOLR_USER:$SOLR_USER /opt/solr /opt/$SOLR

RUN apt-get --assume-yes install vim

EXPOSE 8983
WORKDIR /opt/solr
USER $SOLR_USER
CMD ["/bin/bash", "-c", "/opt/solr/bin/solr -f"]

第二，在构建时不要将代码复制到容器中，请使用 -v 选项将更加灵活。

Second, don't copy the codes to container when building, use -v option will be more flexible.

COPY home/ocscommerce /etc/solr/home

替换为 docker run 命令 -v home / ocscommerce：/ etc / solr / home
