ec2-instance-manager
Set Up
Install python3, pip3 and virtualenv:
sudo apt-get install python3
sudo apt-get install python3-pip
sudo pip3 install virtualenv
Create a virtual environment and activate it:
virtualenv -p python3 ec2
. ec2/bin/activate
#To stop working on ec2 venv use: deactivate
Within the ec2 venv, install the serverless framework:
sudo npm install -g serverless
Package Solution
To create an artifact of entire stack including CloudFormation, run:
serverless package --package ec2-instance-manager
Deployment
The first deployment, the stack needs to be created on cloudformation, so edit serverless.yml to deploy everything together by removing the line individually: true of the service package block and then deploy everything with:
serverless deploy -v
After first deploy, edit serverless.yml adding the line individually: true of the service package block and deploy functions separately:
serverless deploy function --function change
serverless deploy function --function start
serverless deploy function --function stop
Known Issues with deployment
AWS Lambda requires global read permissions on the uploaded zip, otherwise it might return an error that says something like Permission Denied to /path/to/src, to resolve that change your local repository files and directories permissions.
- First, check permission on deployment zip:
$ zipinfo test.zip
Archive: test.zip
Zip file size: 473 bytes, number of entries: 2
-r-------- 3.0 unx 0 bx stor 17-Aug-10 09:37 exlib.py
-r-------- 3.0 unx 234 tx defN 17-Aug-10 09:37 index.py
2 files, 234 bytes uncompressed, 163 bytes compressed: 30.3%
- If there is no global read permission add those to all files and directories of your repository:
$ chmod 644 $(find $(pwd) -type f)
$ chmod 755 $(find $(pwd) -type d)- Generate a new deployment zip. Permissions on the zip now should look like this:
$ zipinfo test.zip
Archive: test.zip
Zip file size: 473 bytes, number of entries: 2
-r--r--r-- 3.0 unx 0 bx stor 17-Aug-10 09:37 exlib.py
-r--r--r-- 3.0 unx 234 tx defN 17-Aug-10 09:37 index.py
