Working with docker running in remote machine

Pre-Condition: User should be added to docker group

Step 1: Add host in ~/.ssh/config

Host <SSH_HOST_ALIAS>
HostName <HOST_IP_OR_HOSTNAME>
User <LOGIN_USERNAME>
IdentityFile <PATH_TO_PRIVATE_KEY>
# Restrict authentication to the specified private key
IdentitiesOnly yes

Step 2: Create Docker contexts using those host aliases.

docker context create [dockercontextName] --docker "host=ssh://HostAlias"

Step 3: Test the connection

docker --context [dockercontextName] ps

Step 4: Switch to the context

docker context use [dockercontextName]

Step 5: To show current active context

docker context show

Clean up

Target Resource	Safe / Default Prune	Aggressive / Complete Prune	What it Removes
Global System	docker system prune	docker system prune -a --volumes	Stopped containers, unused networks, build caches, and images.
Images	docker image prune	docker image prune -a	Default removes "dangling" (untagged) images; -a removes all unused images.
Containers	docker container prune	N/A (Default removes all)	Removes all stopped containers.
Volumes	docker volume prune	docker volume prune --filter all=1	Removes local volumes not used by any remaining containers.
Networks	docker network prune	N/A (Default removes all)	Removes all networks not used by at least one container.
Build Cache	docker builder prune	docker builder prune -a	Frees up cache space generated during image building stages.
