How do I configure a network in Docker?
To configure a network in Docker, use the `docker network create` command to establish a new network. You can specify options such as driver type and subnet settings for customized connectivity.
How do I configure a Docker Swarm?
To configure a Docker Swarm, initialize the swarm with `docker swarm init`, then add nodes with `docker swarm join`. Finally, deploy services using `docker service create`.
How do I configure a network in Docker Swarm?
Configuring a network in Docker Swarm involves creating an overlay network that spans multiple hosts. Use the command `docker network create –driver overlay ` to set it up, enabling seamless communication between services.
How do I configure restart policies in Docker?
To configure restart policies in Docker, use the `–restart` flag with options like `no`, `always`, `unless-stopped`, or `on-failure` during container creation. This ensures containers restart based on specified conditions.
How do I manage configuration in Docker?
Managing configuration in Docker involves using environment variables, configuration files, and Docker secrets. These methods ensure flexibility and security for your applications.
What is a bridge network in Docker?
A bridge network in Docker is a default network type that allows containers to communicate with each other on the same host. It isolates container traffic, enhancing security and organization.
What is a host network in Docker?
A host network in Docker allows containers to share the host’s networking namespace. This means they can communicate directly with the host’s network interfaces, enhancing performance and simplifying configuration.
What is an overlay network in Docker?
An overlay network in Docker is a virtual network that enables communication between containers across multiple Docker hosts, enhancing scalability and isolation in distributed applications.
What is a macvlan network in Docker?
A macvlan network in Docker allows containers to have their own MAC addresses, enabling them to appear as individual devices on the network. This facilitates better network isolation and communication with external services.
What is a none network in Docker?
A “none” network in Docker is a network mode that disables all networking for a container. This means the container cannot communicate with other containers or the host, isolating its operations.
