Elastic beanstalk cannot install packages

Question

I am trying to deploy my application on AWS Elastic Beanstalk. I get this error and cannot fully understand where the problem is.

Below is the code present in .ebextensions/mysite-env.config

 packages: yum: python-devel: [] postgresql-devel: [] container_commands: 01_syncdb: command: "django-admin.py syncdb --noinput" leader_only: true 02_createadmin: command: "scripts/createadmin.py" leader_only: true option_settings: - option_name: WSGIPath namespace: "aws:elasticbeanstalk:container:python" value: "mysite/wsgi.py" - option_name: DJANGO_SETTINGS_MODULE value: "mysite.settings" 

After a few tricks, I figured out a few things

• The above configuration file works after requirements.txt present in the root directory
• It is not possible to install these packages (mentioned above), but I could install it by going into ssh EC2 instance (weird)

The problem with [1] is that I need the above packages to install psycopg2 . So how do I install them first?

When I run these settings, I get the following error:

 [2014-11-19T09:45:19.819Z] INFO [6703] - [CMD-AppDeploy/AppDeployStage0/EbExtensionPreBuild] : Activity execution failed, because: command failed with error code 1: Error occurred during build: Yum does not have postgresql-devel available for installation (Executor::NonZeroExitStatus) 

Then I used the settings below

packages: none: python-devel: [] inclined: postgresql-devel: []

Then I get the following error:

 [2014-11-19T09:47:54.271Z] ERROR [6789] : Command execution failed: [CMD-AppDeploy/AppDeployStage0/EbExtensionPreBuild] command failed with error code 1: Error occurred during build: [Errno 2] No such file or directory (ElasticBeanstalk::ActivityFatalError) at /opt/elasticbeanstalk/lib/ruby/lib/ruby/gems/2.1.0/gems/beanstalk-core-1.0/lib/elasticbeanstalk/activity.rb:189:in `rescue in exec' ... caused by: command failed with error code 1: Error occurred during build: [Errno 2] No such file or directory (Executor::NonZeroExitStatus) 

When can I install these packages directly from ssh , what is the problem with automation? What happened to my settings?

Answer 1

Use postgresql93-devel in yum statement as they updated package names

 packages: yum: python26-devel: [] postgresql93-devel: [] 

Answer 2

I could not find a different way than installing these packages manually.

 packages: yum: ... commands: 01_python_devel_install: command: 'yum install -y python34-devel' 02_postgresql_install: command: 'yum install -y postgresql94 postgresql94-devel' 

I start with an elastic beanstalk, and that doesn't give me a good first impression.

Answer 3

Going the right way according to AWS.

Python 3

 packages: yum: python34-devel: [] postgresql94-devel: [] 

Python 2.7

 packages: yum: python27-devel: [] postgresql94-devel: []
