Apr 21, 2016 Hi all I need to run docker engine on my ubuntu host, but also i need to run an https apache server into it, as consequence, starting docker as second service, i will get 443 port as occupied.

The type of network a container uses, whether it is a bridge, anoverlay, a macvlan network, or a custom networkplugin, is transparent from within the container. From the container’s point ofview, it has a network interface with an IP address, a gateway, a routing table,DNS services, and other networking details (assuming the container is not usingthe none network driver). This topic is about networking concerns from thepoint of view of the container.

Published ports
By default, when you create or run a container using docker create or docker run,it does not publish any of its ports to the outside world. To make a port availableto services outside of Docker, or to Docker containers which are not connected tothe container’s network, use the --publish or -p flag. This creates a firewallrule which maps a container port to a port on the Docker host to the outside world.Here are some examples.
| Flag value | Description |
|---|---|
-p 8080:80 | Map TCP port 80 in the container to port 8080 on the Docker host. |
-p 192.168.1.100:8080:80 | Map TCP port 80 in the container to port 8080 on the Docker host for connections to host IP 192.168.1.100. |
-p 8080:80/udp | Map UDP port 80 in the container to port 8080 on the Docker host. |
-p 8080:80/tcp -p 8080:80/udp | Map TCP port 80 in the container to TCP port 8080 on the Docker host, and map UDP port 80 in the container to UDP port 8080 on the Docker host. |
IP address and hostname
By default, the container is assigned an IP address for every Docker network itconnects to. The IP address is assigned from the pool assigned tothe network, so the Docker daemon effectively acts as a DHCP server for eachcontainer. Each network also has a default subnet mask and gateway.
When the container starts, it can only be connected to a single network, using--network. However, you can connect a running container to multiplenetworks using docker network connect. When you start a container using the--network flag, you can specify the IP address assigned to the container onthat network using the --ip or --ip6 flags.
When you connect an existing container to a different network usingdocker network connect, you can use the --ip or --ip6 flags on thatcommand to specify the container’s IP address on the additional network.
In the same way, a container’s hostname defaults to be the container’s ID inDocker. You can override the hostname using --hostname. When connecting to anexisting network using docker network connect, you can use the --aliasflag to specify an additional network alias for the container on that network.
DNS services
Failed Port Is Already Allocated Issue 1114 Docker For Mac Github Key
By default, a container inherits the DNS settings of the host, as defined in the/etc/resolv.conf configuration file. Containers that use the default bridgenetwork get a copy of this file, whereas containers that use acustom networkuse Docker’s embedded DNS server, which forwards external DNS lookups to the DNSservers configured on the host.
Custom hosts defined in /etc/hosts are not inherited. To pass additional hostsinto your container, refer to add entries to container hosts filein the docker run reference documentation. You can override these settings ona per-container basis.

| Flag | Description |
|---|---|
--dns | The IP address of a DNS server. To specify multiple DNS servers, use multiple --dns flags. If the container cannot reach any of the IP addresses you specify, Google’s public DNS server 8.8.8.8 is added, so that your container can resolve internet domains. |
--dns-search | A DNS search domain to search non-fully-qualified hostnames. To specify multiple DNS search prefixes, use multiple --dns-search flags. |
--dns-opt | A key-value pair representing a DNS option and its value. See your operating system’s documentation for resolv.conf for valid options. |
--hostname | The hostname a container uses for itself. Defaults to the container’s ID if not specified. |
