➡️ postStart: Executed after a container has started. It can be used for tasks that need to be performed once the container is up and running. Initialization and Configuration, Dependency check, Health Checks are some common usecases that are configured here.

➡️ preStop: Executed just before a container is terminated. It provides an opportunity to perform cleanup tasks or gracefully shut down the application before the container stops. Graceful Shutdown, Connection Draining, Notification of Termination are all the things that can be configured here.

Strong knowledge of configuration management tools (Ansible, Puppet, Chef)

To convert from binary to octal, sum the values represented by 'r' (read), 'w' (write), and 'x' (execute) in each set of permissions. For instance, the binary permission 'rwxr-xr-x' translates to the octal permission 755:
- r = 4 (read)
- w = 2 (write)
- x = 1 (execute)
- - = 0 (no permission)

Additionally, the 𝚌𝚑𝚖𝚘𝚍 command can be used with symbolic notation, allowing more direct modifications. For instance:
- To add write permission for the group: 𝚌𝚑𝚖𝚘𝚍 𝚐+𝚠 𝚖𝚢𝚏𝚒𝚕𝚎
- To remove execute permission for others: 𝚌𝚑𝚖𝚘𝚍 𝚘-𝚡 𝚖𝚢𝚏𝚒𝚕𝚎
