我正在构建一个Docker容器,它从bitbucket中提取perl / mojolicious repo,但我遇到了问题。我有这样的Dockerfile:
# DOCKER-VERSION 0.3.4
FROM perl:latest
MAINTAINER My Name myname@name.com
# Update aptitude with new repo
RUN apt-get update
# Install software
RUN apt-get install -y git
# Make ssh dir
RUN mkdir /root/.ssh/
# Copy over private key, and set permissions
ADD repo-key /root/.ssh/id_rsa
# Create known_hosts
RUN touch /root/.ssh/known_hosts
# Add bitbuckets key
RUN ssh-keyscan bitbucket.org >> /root/.ssh/known_hosts
RUN curl -L http://cpanmin.us | perl - App::cpanminus
RUN cpanm Mojolicious
RUN cachebuster=b953b35 git clone -b branch git@bitbucket.org:org/project.git
EXPOSE 8080
WORKDIR project
CMD hypnotoad script/project
而且,在本地,docker build -t name/project .
它建立得很好,并说“成功建造。”
我用repo-key文件将其压缩并将其提供给Elastic Beanstalk,我点击了上传和部署(我成功部署了2048游戏样本,并尝试复制它)。
这回来Dockerrun.aws.json: No such file or directory
。我认为这很奇怪,因为文档说Dockerfile或Dockerrun.aws.json可以独立用于不同的需求。但无论如何,我给了它一个简短的,希望无关紧要的Dockerrun.aws.json,就像这样:
{
"AWSEBDockerrunVersion": "1",
"Ports": [
{"ContainerPort": "8080"}
],
"Volumes": []
}
它仍然失败,现在日志会显示[CMD-AppDeploy/AppDeployStage0/AppDeployPreHook/04run.sh] command failed with error code 1:
并进一步Docker container quit unexpectedly after launch
。
有人可以帮我解决这些问题吗?
答案 0 :(得分:2)
我明白了。问题是默认情况下hypnotoad
在后台运行,这会使容器立即死亡。通过添加-f
标志,它在前台运行,容器仍然存在。我还将CMD
切换为ENTRYPOINT
。
#... same as above except for last line
WORKDIR project
ENTRYPOINT [ "hypnotoad", "-f", "./script/project" ]
你仍然必须向EB提供Dockerfile和Dockerrun.aws.json,但没有明显的原因,但即便如此,它也能正常运行。
