Whether +the input is for a container or pod, Podman will always generate the specification as a Pod. The input may be in the form +of a pod or container name or ID. + +Note that the generated Kubernetes YAML file can be used to re-run the deployment via podman-play-kube(1). + +## OPTIONS: + +**--filename**, **-f**=**filename** + +Output to the given file, instead of STDOUT. If the file already exists, `generate kube` will refuse to replace it and return an error. + +**--service**, **-s** + +Generate a Kubernetes service object in addition to the Pods. Used to generate a Service specification for the corresponding Pod output. In particular, if the object has portmap bindings, the service specification will include a NodePort declaration to expose the service. A +random port is assigned by Podman in the specification. + +## Examples + +Create Kubernetes Pod YAML for a container called `some-mariadb` . +``` +$ sudo podman generate kube some-mariadb +# Generation of Kubenetes YAML is still under development! +# +# Save the output of this file and use kubectl create -f to import +# it into Kubernetes. +# +# Created with podman-0.11.2-dev +apiVersion: v1 +kind: Pod +metadata: + creationTimestamp: 2018-12-03T19:07:59Z + labels: + app: some-mariadb + name: some-mariadb-libpod +spec: + containers: + - command: + - docker-entrypoint.sh + - mysqld + env: + - name: PATH + value: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin + - name: TERM + value: xterm + - name: HOSTNAME + - name: container + value: podman + - name: GOSU_VERSION + value: "1.10" + - name: GPG_KEYS + value: "199369E5404BD5FC7D2FE43BCBCB082A1BB943DB \t177F4010FE56CA3336300305F1656F24C74CD1D8 + \t430BDF5C56E7C94E848EE60C1C4CBDCDCD2EFD2A \t4D1BB29D63D98E422B2113B19334A25F8507EFA5" + - name: MARIADB_MAJOR + value: "10.3" + - name: MARIADB_VERSION + value: 1:10.3.10+maria~bionic + - name: MYSQL_ROOT_PASSWORD + value: x + image: quay.io/baude/demodb:latest + name: some-mariadb + ports: + - containerPort: 3306 + hostPort: 36533 + protocol: TCP + resources: {} + securityContext: + allowPrivilegeEscalation: true + privileged: false + readOnlyRootFilesystem: false + tty: true + workingDir: / +status: {} +``` + +Create Kubernetes Pod YAML for a pod called `demoweb` and include a service. +``` +$ sudo podman generate kube -s demoweb +# Generation of Kubernetes YAML is still under development! +# +# Save the output of this file and use kubectl create -f to import +# it into Kubernetes. +# +# Created with podman-0.12.2-dev +apiVersion: v1 +kind: Pod +metadata: + creationTimestamp: 2018-12-18T15:16:06Z + labels: + app: demoweb + name: demoweb-libpod +spec: + containers: + - command: + - python3 + - /root/code/graph.py + env: + - name: PATH + value: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin + - name: TERM + value: xterm + - name: HOSTNAME + - name: container + value: podman + image: quay.io/baude/demoweb:latest + name: practicalarchimedes + resources: {} + securityContext: + allowPrivilegeEscalation: true + capabilities: {} + privileged: false + readOnlyRootFilesystem: false + tty: true + workingDir: /root/code +status: {} +--- +apiVersion: v1 +kind: Service +metadata: + creationTimestamp: 2018-12-18T15:16:06Z + labels: + app: demoweb + name: demoweb-libpod +spec: + ports: + - name: "8050" + nodePort: 31269 + port: 8050 + protocol: TCP + targetPort: 0 + selector: + app: demoweb + type: NodePort +status: + loadBalancer: {} +``` + +## SEE ALSO +podman(1), podman-container(1), podman-pod(1), podman-play-kube(1) + +## HISTORY +December 2018, Originally compiled by Brent Baude (bbaude at redhat dot com) |
