Docker configuration for production and development environment.

In Production environment following modules have been containerized in docker:

1. C++ log processing server named as anemomind_anemocppserver_1
2. Anemolab web app named as anemomind_anemowebapp_1
3. Mongodb named as anemomongo

In Devlopment Environment:

1. C++ log processing server has been containerized in docker as anemomind_anemocppserver_1.

2. On host machine user can make changes on cpp server code using VS Code IDE and those changes will reflected on container anemomind_anemocppserver_1 also user can build the code on container through host machine.

Pre-requisites

Following packages must be installed:

1. Docker
2. docker-compose
3. VS Code (vs code is needed only for development evnvironment)

Installation

Containerized anemomind can be created through run.sh script.

run.sh takes 1 argument as environment and this argument must be either prod or dev

To create containerized anemomind in Production use:

./run.sh prod

And in Development use:

./run.sh dev

NOTE: In both the environments run.sh will compile and build the code base and hence might take a while running it for the first time.

Usage

In Production

To check that containers are running type following command on the local terminal:

docker container ls 

if containers are running you will see follwing listing

(NOTE: container IDs will be different)

To interact and to examine the contents of the containers type following commands on local machine:

docker exec -it {container_name/container_id} bash 

Example:

docker exec -it anemomind_anemowebapp_1 bash (use sh instead of bash in case of anemomind container)

NOTE: All containers related logs will appear on terminal from where run.sh executed.

To check logs of anemomind_anemocppserver_1 run:

docker exec -it anemomind_anemocppserver_1 bash
tail -f /var/log/cron.log

To check cron job running on anemomind_anemocppserver_1 run:

docker exec -it anemomind_anemocppserver_1 bash
crontab -e (OR) cat /etc/cron.d/anemo-cron

In Development

To check that container is running type following command on the local terminal:

 docker container ls 

if containers are running you will see follwing listing

CONTAINER ID        IMAGE                      COMMAND                  CREATED             STATUS              PORTS                                 NAMES

NOTE: container ID will be different)

Steps to build Cpp Server on anemomind_anemocppserver_1 container:

1. set root password of container:

   a. login to anemomind_anemocppserver_1 as:

    docker exec -it anemomind_anemocppserver_1 bash
   

   b. In anemomind_anemocppserver_1 container type: passwd

   NOTE: user can also use key-based authentication by copying security keys to container as:

   ssh-copy-id -p 7188 root@localhost
   

2. On host machine:
   a. Open anemomind project in VS Code IDE, make required changes on cpp server code and save the changes.
   b. Press ctrl+shift+B, a popup with name build will appear, click on the popup.
   c. Accept the keys and then enter the root password of anemomind_anemocppserver_1 on VS Code Terminal to start the build process.
