an exported port on a running container the provided container needs to be up and running for example it can be started in advance using docker run within an ephemeral instance the exposed endpoint is encrypted with tls and secured with namespace authentication so whoever has access to the workspace where the ephemeral environment was created in will also have access to the endpoint note only http services can currently be exposed usage nsc expose container instance i d container nam e container_port port port name ingress nam e source docker containerd output plain json example in the example below we first create an ephemeral instance then ssh into the instance start the nginx container with docker run and then expose it using nsc expose container create an ephemeral instance nsc create created instance oiepencpc41im deadline 2023 04 25t09 46 03z ssh into the created instance nsc ssh oiepencpc41im and start nginx container within the created instance oiepencpc41im docker run name nginx foobar p 80 80 d nginx then expose port 80 using the nsc expose container command nsc expose container oiepencpc41im container nginx foobar container_port 80 exported port 80 from nginx foobar 20e97bc453c936a9665dd6ce75e0168c92a689cc92214303a87fc19a https nginx foobar j239700 oiepencpc41im fra1 namespaced app now you can visit the provided url https nginx foobar j239700 oiepencpc41im fra1 namespaced app in your browser and use your namespace credentials for authentication options container name to specify a name of a container to expose this option is required container_port port port exports the specified ports separated by commas as public ingresses if the option is not provided all the exported ports would be exposed name name set the name of the exposed ingress setting a name is only permitted when exposing a single port by default ingress names will be generated by namespace source source to specify the container runtime which was used to run the container supported options are docker and containerd by default docker is used to lookup running containers o type specifies the output format supported options are json and plain by default plain output format is used all export one ingress for each exported port of each running container wildcard if set generate a wildcard ingress for the exposed container port can only be used when exposing a single port last
