# Logs-Management

Docker multiple containers logs management into one *.json file

## [Implementation](https://github.com/af4092/Logs-Management/tree/main/docker_logs_test)

1. We first build two `node.js` source files one for `sender.js` which sends message to server and another one is `server.js` server which runs on `port:3001`.

2. Then we make `Dockerfile` for both `sender.js` and `server.js` applications.  

     - `Dockerfile.server` is as following:

       

       ```

        # Use a base image

         FROM node:latest

        # Set the working directory

         WORKDIR /app

        # Copy the server file into the container

         COPY server.js .

        # Expose port 3001

         EXPOSE 3001

        # Run the Node.js server

         CMD ["node", "server.js"]

       ```

       

     - `Dockerfile.sender` is as following:

  

       ```

       # Use a base image

          FROM node:latest

       # Set the working directory

          WORKDIR /app

       # Copy the sender file into the container

          COPY sender.js .

       # Run the message sender

          CMD ["node", "sender.js"]

       ```

3. After making dockerfiles, we build `Docker image` from Dockerfiles with the following commands:

   ```

   $ docker build -t server:v0.1 -f Dockerfile.server .

   $ docker build -t sender:v0.1 -f Dockerfile.sender .

   ```

     


         

      


4. Then we run the image inside the Docker container with the following commands:

   ```

   $ docker run -d -p 3001:3001 --name server server:v0.1

   $ docker run -d --name sender sender:v0.1

   ```

   

 


         

      


5. We write script file to collect Docker containers logs into one `*.json` file. After running previous images in the Docker containers, we run `collect_logs.sh` script with the following command:

     ```

     $ ./collect_logs.sh

     # then we get following answer from the terminal

     $ Logs collected and saved to logs.json

     ```

6. Then we go inside the `logs.json` file to check the logs output:



         

      


```diff

- To Do:

- As you've seen currently logs are being gathered only for one container and other container logs are not being tracked. So script source should be reconfigured to handle the issue

```
