将环境variables传递给Docker容器

目前使用Elastic Beanstalk来运行Docker容器，我需要将重要的信息作为环境variables传递给我的容器。

我目前的Dockerrun.aws.json看起来像这样：

{ "AWSEBDockerrunVersion": "1", "Image": { "Name": "b2boost/rabbitelasticdockstash", "Update": "true" }, "Ports": [ { "ContainerPort": "80" } ], "environment": [ { "name": "RABBITMQ_HOST", "value": "RABBITMQ_HOST" }, { "name": "RABBITMQ_PASSWORD", "value": "RABBITMQ_PASSWORD" }, { "name": "RABBITMQ_USER", "value": "RABBITMQ_USER" }, { "name": "RABBITMQ_VHOST", "value": "RABBITMQ_VHOST" }, { "name": "ELASTICSEARCH_HOST", "value": "ELASTICSEARCH_HOST" }, { "name": "ELASTICSEARCH_PASSWORD", "value": "ELASTICSEARCH_PASSWORD" }, { "name": "ELASTICSEARCH_PORT", "value": "ELASTICSEARCH_PORT" }, { "name": "ELASTICSEARCH_PROTOCOL", "value": "ELASTICSEARCH_PROTOCOL" }, { "name": "ELASTICSEARCH_USER", "value": "ELASTICSEARCH_USER" } ], "Volumes": [ ], "Logging": "/var/log/eb-activity.log" } 

但是这不起作用。 当SSH到我的beanstalk实例，然后获取环境variables的内容，我可以看到他们没有初始化：

 [ec2-user@myip ~]$ sudo docker exec goofy_curie env PATH=/opt/logstash/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:bin HOSTNAME=HOSTNAME LANG=C.UTF-8 JAVA_VERSION=7u79 JAVA_DEBIAN_VERSION=7u79-2.5.5-1~deb8u1 LOGSTASH_MAJOR=1.5 LOGSTASH_VERSION=1:1.5.1-1 HOME=/root 

我如何在我的容器中设置环境variables？ Dockerrun.aws.json似乎不适合我。

Answer 1

单个容器的Dockerrun.aws.json中不允许使用“environment”字段。

但是，您可以使用以下过程在.config文件中指定环境variables（有关更多信息，请参阅文档 ）：

1. 创build一个文件夹.ebextensions
2. 在文件夹中创build一个.config文件
3. 填写configuration文件：

 option_settings：  
   -  option_name：RABBITMQ_HOST
    值：RABBITMQ_HOST
   -  option_name：RABBITMQ_PASSWORD
    值：RABBITMQ_PASSWORD
   -  option_name：RABBITMQ_USER
    值：RABBITMQ_USER
   -  option_name：RABBITMQ_VHOST
    值：RABBITMQ_VHOST
   -  option_name：ELASTICSEARCH_HOST
    值：ELASTICSEARCH_HOST
   -  option_name：ELASTICSEARCH_PASSWORD
    值：ELASTICSEARCH_PASSWORD
   -  option_name：ELASTICSEARCH_PORT
    价值：ELASTICSEARCH_PORT
   -  option_name：ELASTICSEARCH_PROTOCOL
    值：ELASTICSEARCH_PROTOCOL
   -  option_name：ELASTICSEARCH_USER
    值：ELASTICSEARCH_USER

5. 将.ebextensions文件和Dockerrun.aws.json一起压缩并上传到Beanstalk
