Question

在部署我的Django项目时,由于<代码>,没有配置数据库环境。 RDS_HOSTNAME in os.environ Return false。事实上,在部署时没有环境财产。所有这些财产都是在部署后提供的。

滚动环境:<条码>/opt/elgalbeanstalk/bin/get-config environment>。

{"DJANGO_SETTINGS_MODULE":"myApp.settings","PYTHONPATH":"/var/app/venv/staging-LQM1lest/bin:$PYTHONPATH","RDS_DB_NAME":"ebdb","RDS_HOSTNAME":"xxxx.amazonaws.com","RDS_PASSWORD":"xxxx","RDS_PORT":"xxxx","RDS_USERNAME":"xxxx"}

所有RDS预先确定的财产都是固定的,但是仍然有一些<代码>os.environ无法阅读。

<代码>制定>py文档:

# [...]

if  RDS_HOSTNAME  in os.environ:
    DATABASES = {
         default : {
             ENGINE :  django.db.backends.mysql ,
             NAME : os.environ[ RDS_DB_NAME ],
             USER : os.environ[ RDS_USERNAME ],
             PASSWORD : os.environ[ RDS_PASSWORD ],
             HOST : os.environ[ RDS_HOSTNAME ],
             PORT : os.environ[ RDS_PORT ],
        }
    }

# [...]

我是否必须作任何改动,以便在部署时提供这些财产?

Answer 1

象这样的种子是一种严重的诱杀,美国妇女联盟对此毫不犹豫。我几乎没有办法完成这项工作,但所有这些努力都需要进入EB环境,并做一些手工工作。

Solution 1

A. 创建协会秘密管理人
www.un.org/chinese/ga/president
然后去到宇航科学院用户群,去到Roles。从那以后,你可以将政策附在秘密管理人员的上司上。
一旦完成,就部署该项目。
然后,对环境的标识(eb ssh environment_name)。

Solution 2

Edit .bash_profile and add export these variables at the end of the file:

 export RDS_DB_NAME=your_dbname
 export RDS_USERNAME=user
 export RDS_PASSWORD=pass
 export RDS_HOSTNAME=host_endpoint
 export RDS_PORT=3306

页: 1
现在你可以部署项目。

Solution 3

Set all environment properties in EB environment s configuration. (Go to Configuration->Software->Edit->Environment properties and add the key and values).

2. 结论在<代码>制定时添加这一氮。

    from pathlib import Path
    import os
    import subprocess
    import ast


    def get_environ_vars():
        completed_process = subprocess.run(
            [ /opt/elasticbeanstalk/bin/get-config ,  environment ],
            stdout=subprocess.PIPE,
            text=True,
            check=True
        )

        return ast.literal_eval(completed_process.stdout)

Go to Database section and replace it with this snippet

 if  RDS_HOSTNAME  in os.environ:
     DATABASES = {
          default : {
              ENGINE :  django.db.backends.mysql ,
               NAME : os.environ[ RDS_DB_NAME ],
               USER : os.environ[ RDS_USERNAME ],
               PASSWORD : os.environ[ RDS_PASSWORD ],
               HOST : os.environ[ RDS_HOSTNAME ],
               PORT : os.environ[ RDS_PORT ],
     }
 }
 else:
     env_vars = get_environ_vars()
     DATABASES = {
          default : {
          ENGINE :  django.db.backends.mysql ,
          NAME : env_vars[ RDS_DB_NAME ],
          USER : env_vars[ RDS_USERNAME ],
          PASSWORD : env_vars[ RDS_PASSWORD ],
          HOST : env_vars[ RDS_HOSTNAME ],
          PORT : env_vars[ RDS_PORT ],
     }
 }

项目的实施。
流向环境(eb ssh environment_name)。

最后,<代码>python3管理.pymigration。

Conclusion:

Solution 1 is little complex and secret manager is not free (30 days trial only).
Solution 2 is simplest one but I do not recommend tempering any file manually on EB.
Solution 3 is a clean solution which I will use. This solution also takes care of this bug fix in future.

Answer 2

为了在该系统中使用环境特性,例如,管理传承(使用遗体)的传承,你可以简单地管理:

/opt/elasticbeanstalk/bin/get-config environment | jq -r "to_entries|map("export (.key)= (.value|tostring) ")|.[]" >> /home/ec2-user/.bash_profile

在你通过SSH标出时,将添加以下所有推进剂: 当然,最好在指挥下:科室。

Answer 3

在欧共体2级中提供环境变量的官方亚太观测所解决方案也确定了这一问题:

Answer 4

以@Jarek所写文章为基础。 D AWS Elgal-Beanstalk env Variablestters ,我们采取了一种额外做法,使你能够与Sos.environment.get(c)在该项目中使用python的方法。我们建立了一个进程。 sh 执行:

source /etc/profile.d/sh.local
source /var/app/venv/[your_staging]/bin/activate
python your_file.py

Answer 5

我得以通过:

Encoding my secrets with base64 encoder
Setting the environment variables with encoded values
Decoding the encoded variables while reading inside Django settings

例-假设我们想读环境变量RDS_PASSWORD=@#%^&。

<>Step 1: 将我们的密码与基64统一起来。能够使用以下简称:

In [1]: import base64

In [2]: password = b @#$%^& 

In [3]: base64.b64encode(password)
Out[3]: b QCMkJV4m

Step 2: Setting the environment variable in Elastic Beanstalk environment configuration (Go to your EB environment Configuration->Updates, monitoring, and logging->Edit->Environment properties)

<>3>标准: 在你的Django服务环境中添加逻辑,将这一变量加以编码。 y

DATABASES = {
     default : {
         ENGINE :  django.db.backends.postgresql ,
         NAME : os.environ[ RDS_DB_NAME ],
         USER : os.environ[ RDS_USERNAME ],
         PASSWORD : base64.b64decode(os.environ[ RDS_PASSWORD ]).decode( utf-8 ),
         HOST : os.environ[ RDS_HOSTNAME ],
         PORT : os.environ[ RDS_PORT ],
    }
}

图64所示特征

[A-Z]
[a-z]
[0-9]
[+, /, = (For Padding)]

由EB环境变量值支持的特性

Values can contain any alphanumeric characters, white space, and the following symbols: _ . : / = + - @ "

When compared to other solutions in this post, I find this solution much cleaner

Answer 6

你们可以做以下工作,把环境价值扩大到目前的致命环境:

eval $(/opt/elasticbeanstalk/bin/get-config environment | jq -r "to_entries|map("export (.key)= (.value|tostring) ")|.[]")

这将使埃尔伯兰群岛的变量与你出口这些变量相类似:

export Xmx= 12888m 
export HEAP_DUMP_PATH= /heapdumps 
export ENVIRONMENT= qa
