Tech

  • Python (3.6+, recommended)
  • Serverless Framework (IaaC framework that organises code as per Cloud/AWS infra)
  • Node / NPM (for serverless framework)
  • Optional, but recommended: AWS CLI, virtual environment, brew

Step 1: Install & Configure vendor libraries/packages

A) Install Python virtual environment

$ [sudo] apt-get install python3
$ [sudo] apt-get install python3-pip
$ python3 -v
# Update ~/.bash_profile or ~/.bashrc or $PATH variable, if required, to set default python version
$ [sudo] pip3 install virtualenv
## OR any virtual environment setup of your choice ##

**B) Create project directory of your choice & activate virtual environment

$ mkdir serverless-workshop && cd serverless-workshop
serverless-workshop>$  which python3

/usr/local/bin/python3

serverless-workshop>$  virtualenv -p /usr/local/bin/python3 serverless-workshop

Running virtualenv with interpreter /usr/local/bin/python3 Already using interpreter /usr/local/opt/python/bin/python3.7 Using base prefix '/usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7' New python executable in /Users/sejal/serverless/serverless-workshop/serverless-workshop/bin/python3.7 Also creating executable in /Users/sejal/serverless/serverless-workshop/serverless-workshop/bin/python Installing setuptools, pip, wheel... done.

serverless-workshop>$  source serverless-workshop/bin/activate

(serverless-workshop) serverless-workshop>$ C) Install node/npm

MAC USERS

Install brew:

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
$ brew update
$ brew doctor

Install node/npm:

$ brew install node
## OR ##
$ brew install npm

Check version (Should be Node.js 6.x or later):

$ node -v
## OR ##
$ npm -v

D) Install serverless framework

$ [sudo] npm install -g serverless
$ serverless -v
## OR ##
$ sls -v

Update ~/.bash_profile or ~/.bashrc and/or $PATH env variable, if required

Step 2: Configure AWS / IAM access on local

**A) Install ** aws cli (OPTIONAL) MAC USERS

$ pip install awscli --ignore-installed six
$ aws --version

Based on the email with the creds you must have received for this workshop, configure your IAM key-pair. Contact Administrator/workshop owner for any issues. **B) Configure awscli **

$ aws configure --profile <any-profile-name>

AWS Access Key ID [None]: <ACCESS-KEY-ID>

AWS Secret Access Key [None]: <SECRET-KEY>

Default region name [None]: eu-west-1 Default output format [None]: <blank>

$ cat ~/.aws/credentials
>

[<any profile name>]
AWS_ACCESS_KEY_ID=<ACCESS-KEY-ID>
AWS_SECRET_ACCESS_KEY=<SECRET-KEY>

Step 3: Configure serverless

**A) Configure serverless framework with AWS

$ serverless config credentials --provider aws --key <ACCESS-KEY-ID> --secret <SECRET-KEY> --profile <any-profile-name> --o
$ cat ~/.aws/credentials

[<any-profile-name>]
AWS_ACCESS_KEY_ID=<ACCESS-KEY-ID>
AWS_SECRET_ACCESS_KEY=<SECRET-KEY>

B) Test AWS connection

To check if your local is connected to AWS-Postman-Staging account

$ aws s3 ls
## OR ##
$ aws s3 ls --profile <any-profile-name>

You should see a list of existing buckets present on this AWS-account.
