What is Ansible →
➡️ Ansible is DevOps tool and it is similar like chef means it is a Configuration management tool let’s Begins with a Story → suppose you have a big organisation which have 100’s of servers Now a task is came to install git on that 100’s of servers …man responsible for doing this is System Administrator who is doing this manually which takes a lot of time…

guys!!!! we have that tool and that is Ansible→ A Configuration Management Tool…..
➡️ But !! But !! But !! First you need to connect all the nodes to ansible server which is done manually after that you will be able to automate the things…..
➡️ configuration management →It is a method through which we automate admin tasks.
➡️ It automates the task which the system administrator doing manually

Configuration management tool is of 2 types →
➡️ Pull based → In Pull Based it periodically check for the update from the main server to the nodes if update available it automatically install on the nodes connected with the server → chef and puppet is a pull based config tool.

➡️ Push based → In push based nodes is not going to the main server for the update the update is pushed to the nodes automatically for example the update of apps is pushed to your phone play store now it’s your choice whether you update or not → push based tool is Ansible when you need control in your hands so you take control of your own server for updating.

History of Ansible →
➡️ Michael Dehan developed Ansible in Feb 2012
➡️ Red Hat acquired the Ansible tool in 2015.
➡️ Ansible is available for RHEL, Debian, cent OS, Oracle Linux.
➡️ It is developed in Python background and also in Windows PowerShell.
➡️ You Can use this tool whether your server are in on premises or in the cloud.
➡️ It converted your code into infrastructure means you can say that it is a little bit called an Infrastructure building tool.

Linux 🐧File Permissions Explained

Linux file 💻 permissions are crucial for system security and management. Here's a quick overview to help you understand how they work.

Each file and directory in Linux has a set of permissions that determine who can read, write, or execute them. These permissions are represented by a string of characters, such as -rwxr-xr--.

➡️The permissions string is divided into 4 parts:

1. File Type: The first character indicates the type of file. A dash - means it's a regular file, while d denotes a directory.
2. Owner Permissions: The next three characters show the owner's permissions. In rwx, r stands for read, w for write, and x for execute.
3. Group Permissions: The following three characters represent the group's permissions.
4. Others Permissions: The last three characters indicate the permissions for all other users.

➡️Permissions can also be represented numerically using a three-digit code:
- 4 for read (r)
- 2 for write (w)
- 1 for execute (x)

Each digit sums the permissions for the owner, group, and others. For example, 755 translates to:
- Owner: rwx (4+2+1=7)
- Group: r-x (4+1=5)
- Others: r-x (4+1=5)

Use the chmod command to change permissions. For example, chmod 755 filename sets the file permissions to rwxr-xr-x.

➡️Key Takeaways

- Read (r): View file contents.
- Write (w): Modify file contents.
- Execute (x): Run the file as a program.

Understanding and managing file permissions is vital for maintaining system security and ensuring proper access control. Make sure you regularly check and update permissions to keep your Linux environment secure.

🔔 𝐇𝐞𝐫𝐞 𝐚𝐫𝐞 𝐬𝐨𝐦𝐞 𝐜𝐨𝐦𝐦𝐨𝐧 𝐞𝐫𝐫𝐨𝐫𝐬 𝐚𝐧𝐝 𝐢𝐬𝐬𝐮𝐞𝐬 𝐰𝐞 𝐨𝐟𝐭𝐞𝐧 𝐞𝐧𝐜𝐨𝐮𝐧𝐭𝐞𝐫 𝐰𝐡𝐞𝐧 𝐰𝐨𝐫𝐤𝐢𝐧𝐠 𝐰𝐢𝐭𝐡 𝐃𝐨𝐜𝐤𝐞𝐫:

➡️ 1.𝐈𝐦𝐚𝐠𝐞 𝐍𝐨𝐭 𝐅𝐨𝐮𝐧𝐝: You might encounter this error when trying to run a container with an image that doesn't exist locally or on the specified Docker registry. Ensure that you've pulled the image or that the image name and tag are correct.

➡️ 2.𝐏𝐞𝐫𝐦𝐢𝐬𝐬𝐢𝐨𝐧 𝐃𝐞𝐧𝐢𝐞𝐝: Docker containers often run as non-root users for security reasons. If your application requires access to certain resources or directories, make sure you've set the appropriate file permissions and user/group settings within the container.

➡️ 3.𝐏𝐨𝐫𝐭 𝐂𝐨𝐧𝐟𝐥𝐢𝐜𝐭𝐬: Trying to run multiple containers that use the same host port can lead to port conflicts. Ensure that the ports you specify in the docker run command do not conflict with existing ports in use on your host system.

➡️ 4.𝐎𝐮𝐭 𝐨𝐟 𝐃𝐢𝐬𝐤 𝐒𝐩𝐚𝐜𝐞: Docker uses disk space for images, containers, and logs. Over time, this can consume a significant amount of disk space. Periodically clean up unused images and containers using the docker system prune command.

➡️ 5.𝐂𝐨𝐧𝐭𝐚𝐢𝐧𝐞𝐫 𝐂𝐫𝐚𝐬𝐡: Containers may crash for various reasons, such as misconfiguration or application issues. Use docker logs <container_name> to check the container logs for error messages that can help diagnose the problem.

➡️ 6.𝐃𝐨𝐜𝐤𝐞𝐫 𝐁𝐮𝐢𝐥𝐝 𝐅𝐚𝐢𝐥𝐮𝐫𝐞𝐬: Issues may arise during the build process of a Docker image. Common problems include incorrect Dockerfile syntax, missing files or dependencies, and network problems while downloading packages during the build.

➡️ 7.𝐍𝐞𝐭𝐰𝐨𝐫𝐤𝐢𝐧𝐠 𝐏𝐫𝐨𝐛𝐥𝐞𝐦𝐬: Docker containers can have connectivity problems if not properly configured. Ensure that the container is attached to the correct network, that firewalls are not blocking required ports, and that DNS settings are correct.

➡️ 8.𝐕𝐨𝐥𝐮𝐦𝐞 𝐌𝐨𝐮𝐧𝐭 𝐄𝐫𝐫𝐨𝐫𝐬: Failing to properly mount volumes can result in data loss or incorrect behavior. Double-check the paths and permissions when using the -v flag in docker run or docker-compose.

➡️ 9.𝐑𝐞𝐬𝐨𝐮𝐫𝐜𝐞 𝐂𝐨𝐧𝐬𝐭𝐫𝐚𝐢𝐧𝐭𝐬: Docker containers can consume significant CPU and memory resources. Make sure you allocate appropriate resources using the --cpu and --memory flags when running containers.

➡️ 10.𝐈𝐦𝐚𝐠𝐞 𝐕𝐮𝐥𝐧𝐞𝐫𝐚𝐛𝐢𝐥𝐢𝐭𝐢𝐞𝐬: Using outdated or insecure base images can introduce security vulnerabilities. Regularly update your Docker images and use tools like Clair or Trivy to scan for vulnerabilities.

➡️ 11.𝐑𝐞𝐬𝐨𝐮𝐫𝐜𝐞 𝐋𝐞𝐚𝐤𝐬: Containers should clean up after themselves when they exit. Be cautious about resource leaks, such as leaving behind orphaned processes or unreleased file handles.
