Mastering Docker Networking: Exposing Ports Only to Other Containers

~ Tom's IT Cafe ~ Leave a comment

Docker networks are virtual networks created by Docker to enable communication between Docker containers, allowing them to connect to and communicate with each other or to non-Docker workloads. Containers inside the Docker network can talk to each other by sharing packets of information, and each container sees a network interface with an IP address, a gateway, a routing table, DNS services, and other networking details. By default, the container gets an IP address for every Docker network it attaches to, and when a container starts, it can only attach to a single network, using the –network flag. However, you can connect a running container to multiple networks using the docker network connect command.

A Deep Dive into Ansible Vault: Safeguarding Your Sensitive Data

~ Tom's IT Cafe ~ Leave a comment

Ansible Vault is a feature of Ansible that allows you to encrypt sensitive data such as passwords or keys in encrypted files, rather than as plaintext in playbooks or roles. This provides the ability to secure any sensitive data that is necessary to successfully run Ansible projects. Ansible Vault uses the AES 256 algorithm to provide symmetric encryption, which means that it uses the same password for encrypting and decrypting files. The ansible-vault command is the main interface for managing encrypted content within Ansible, and it is used to initially encrypt files and subsequently used to view, edit, or decrypt the data. Ansible Vault is especially useful if you have confidential data that you want to secure and prevent from being publicly exposed.
