ports
Expose ports.
SHORT SYNTAX
Either specify both ports (HOST:CONTAINER), or just the container port (a random host port will be chosen).
Note: When mapping ports in the
HOST:CONTAINERformat, you may experience erroneous results when using a container port lower than 60, because YAML will parse numbers in the formatxx:yyas sexagesimal (base 60). For this reason, we recommend always explicitly specifying your port mappings as strings.
ports:
- "3000"
- "3000-3005"
- "8000:8000"
- "9090-9091:8080-8081"
- "49100:22"
- "127.0.0.1:8001:8001"
- "127.0.0.1:5000-5010:5000-5010"
- "6060:6060/udp"
LONG SYNTAX
The long form syntax allows the configuration of additional fields that can’t be expressed in the short form.
-
target: the port inside the container -
published: the publicly exposed port -
protocol: the port protocol (tcporudp) -
mode:hostfor publishing a host port on each node, oringressfor a swarm mode port which will be load balanced.
ports:
- target: 80
published: 8080
protocol: tcp
mode: host
Note: The long syntax is new in v3.2
