How to Configure Consul KV Using Docker

Consul by HashiCorp is a versatile tool that serves multiple functions in a modern DevOps environment. It’s widely used for service discovery, health checks, load balancing, and, notably, as a distributed key-value (KV) store. The KV store in Consul is perfect for storing dynamic configuration data, feature flags, secrets, and metadata in a highly available, consistent manner across your infrastructure such that it can be dynamically accessed by services in a distributed system. Using Docker to configure Consul’s KV store allows for quick setup and isolated environments, making it ideal for testing and development.

In which folder should the image downloaded by docker be placed?

In which folder should the image downloaded by docker be placed?

Docker images are stored in the /var/lib/docker/image folder by default. Docker stores images in a hierarchical manner: when a new image is downloaded, Docker checks whether it already exists in local storage. If it does not exist, Docker will download the image from the repository and store it in the image folder. You can change the storage location by setting the docker-root flag. Docker also provides other storage options such as distributed storage, remote storage, and custom storage drivers.
