问题描述
这是我第一次尝试创建 Docker 映像,我希望有人可以帮助我.我的 Dockerfile 大致是这样的:
This is my very first try to create a Docker image and I'm hoping someone can help me out. My Dockerfile looks roughly like this:
FROM mybaseimage:0.1
MAINTAINER ...
ENV JAVA_HOME /usr/lib/jvm/java-7-openjdk-amd64
RUN sed 's/main$/main universe/' -i /etc/apt/sources.list
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update
RUN apt-get install -y openjdk-7-jre && apt-get clean &&
mkdir temp_dir && cd temp_dir &&
${JAVA_HOME}/bin/jar -xvf somejar.jar &&
cd ..
ENTRYPOINT ["somescript.sh"]
基本上我只是安装 Java,所以我可以扩展一个 jar 文件.当我运行我的 makefile 时,我收到以下错误:
Basically I'm only installing Java so I can expand a jar file. When I run my makefile I get the following error:
/bin/sh: 1:/usr/lib/jvm/java-7-openjdk-amd64: 权限被拒绝
/bin/sh: 1: /usr/lib/jvm/java-7-openjdk-amd64: Permission denied
我一直在尝试遵循以下示例:https://registry.hub.docker.com/u/barnybug/openjdk-7-jre/dockerfile/
I've been trying to follow this example:https://registry.hub.docker.com/u/barnybug/openjdk-7-jre/dockerfile/
评论中的每个请求都是我的makefile:
per request in the comment here is my makefile:
DOCKER_REGISTRY=registry.mycompany.com
DOCKER_IMAGE=appimage-myapp
DOCKER_TAG=3.0
SUDO=
ARCHIVE_NAME=$(DOCKER_IMAGE):$(DOCKER_TAG)
REPO_ARCHIVE_NAME=$(DOCKER_REGISTRY)/$(ARCHIVE_NAME)
BASE_IMAGE_ARCHIVE=$(DOCKER_IMAGE)_$(DOCKER_TAG).tar.gz
all: $(BASE_IMAGE_ARCHIVE)
.PHONY: docker_image
docker_image: Dockerfile
$(SUDO) docker build -t $(ARCHIVE_NAME) .
$(BASE_IMAGE_ARCHIVE): docker_image
$(SUDO) docker tag -f $(ARCHIVE_NAME) $(REPO_ARCHIVE_NAME)
$(SUDO) docker push $(REPO_ARCHIVE_NAME)
$(SUDO) docker save $(ARCHIVE_NAME) | gzip -c > $@
$(SUDO) docker rmi $(REPO_ARCHIVE_NAME)
我和它一起运行
make docker_image SUDO=sudo
推荐答案
我能够通过以下步骤安装 OpenJDK 8(取自 这里).我的 Dockerfile 继承自 phusion/baseimage-docker,它基于 Ubuntu 16.04 LTS.
I was able to install OpenJDK 8 via the steps below (taken from here). My Dockerfile inherits from phusion/baseimage-docker, which is based on Ubuntu 16.04 LTS.
# Install OpenJDK-8
RUN apt-get update &&
apt-get install -y openjdk-8-jdk &&
apt-get install -y ant &&
apt-get clean;
# Fix certificate issues
RUN apt-get update &&
apt-get install ca-certificates-java &&
apt-get clean &&
update-ca-certificates -f;
# Setup JAVA_HOME -- useful for docker commandline
ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64/
RUN export JAVA_HOME
要改为安装 OpenJDK 7,您可能需要预先添加
To install OpenJDK 7 instead, you may need to prepend
add-apt-repository ppa:openjdk-r/ppa
这样第一步就变成了
# Install OpenJDK-7
RUN add-apt-repository ppa:openjdk-r/ppa &&
apt-get update &&
apt-get install -y openjdk-7-jdk &&
apt-get install -y ant &&
apt-get clean;
我希望这会有所帮助.
