Welcome to the deployment tool for GlusterFS on Kubernetes and OpenShift.
Before getting started, this script has some requirements of the execution
environment and of the container platform that you should verify.
The client machine that will run this script must have:
Administrative access to an existing Kubernetes or OpenShift cluster
Access to a python interpreter 'python'
Each of the nodes that will host GlusterFS must also have appropriate firewall
rules for the required GlusterFS ports:
2222 - sshd (if running GlusterFS in a pod)
24007 - GlusterFS Management
24008 - GlusterFS RDMA
49152 to 49251 - Each brick for every volume on the host requires its own
port. For every new brick, one new port will be used starting at 49152. We
recommend a default range of 49152-49251 on each host, though you can adjust
this to fit your needs.
The following kernel modules must be loaded:
dm_snapshot
dm_mirror
dm_thin_pool
For systems with SELinux, the following settings need to be considered:
virt_sandbox_use_fusefs should be enabled on each node to allow writing to
remote GlusterFS volumes
In addition, for an OpenShift deployment you must:
Have 'cluster_admin' role on the administrative account doing the deployment
Add the 'default' and 'router' Service Accounts to the 'privileged' SCC
Have a router deployed that is configured to allow apps to access services
running in the cluster
Do you wish to proceed with deployment?
Using Kubernetes CLI.
Using namespace "default".
Checking for pre-existing resources...
GlusterFS pods ... found.
deploy-heketi pod ... not found.
heketi pod ... found.
gluster-s3 pod ... not found.
Error: unknown flag: --show-all
Examples:
List all pods in ps output format.
kubectl get pods
List all pods in ps output format with more information (such as node name).
kubectl get pods -o wide
List a single replication controller with specified NAME in ps output format.
kubectl get replicationcontroller web
List deployments in JSON output format, in the "v1" version of the "apps" API group:
kubectl get deployments.v1.apps -o json
List a single pod in JSON output format.
kubectl get -o json pod web-pod-13je7
List a pod identified by type and name specified in "pod.yaml" in JSON output format.
kubectl get -f pod.yaml -o json
List resources from a directory with kustomization.yaml - e.g. dir/kustomization.yaml.
kubectl get -k dir/
Return only the phase value of the specified pod.
kubectl get -o template pod/web-pod-13je7 --template={{.status.phase}}
List resource information in custom columns.
kubectl get pod test-pod -o custom-columns=CONTAINER:.spec.containers[0].name,IMAGE:.spec.containers[0].image
List all replication controllers and services together in ps output format.
kubectl get rc,services
List one or more resources by their type and names.
kubectl get rc/web service/frontend pods/web-pod-13je7
Options:
-A, --all-namespaces=false: If present, list the requested object(s) across all namespaces. Namespace in current context is ignored even if specified with --namespace.
--allow-missing-template-keys=true: If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats.
--chunk-size=500: Return large lists in chunks rather than all at once. Pass 0 to disable. This flag is beta and may change in the future.
--field-selector='': Selector (field query) to filter on, supports '=', '==', and '!='.(e.g. --field-selector key1=value1,key2=value2). The server only supports a limited number of field queries per type.
-f, --filename=[]: Filename, directory, or URL to files identifying the resource to get from a server.
--ignore-not-found=false: If the requested object does not exist the command will return exit code 0.
-k, --kustomize='': Process the kustomization directory. This flag can't be used together with -f or -R.
-L, --label-columns=[]: Accepts a comma separated list of labels that are going to be presented as columns. Names are case-sensitive. You can also use multiple flag options like -L label1 -L label2...
--no-headers=false: When using the default or custom-column output format, don't print headers (default print headers).
-o, --output='': Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath].
--raw='': Raw URI to request from the server. Uses the transport specified by the kubeconfig file.
-R, --recursive=false: Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
-l, --selector='': Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2) --server-print=true: If true, have the server return the appropriate table output. Supports extension APIs and CRDs.
--show-kind=false: If present, list the resource type for the requested object(s).
--show-labels=false: When printing, show all labels as the last column (default hide labels column)
--sort-by='': If non-empty, sort list types using this field specification. The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
--template='': Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview].
-w, --watch=false: After listing/getting the requested object, watch for changes. Uninitialized objects are excluded if no object name is provided.
--watch-only=false: Watch for changes to the requested object(s), without listing/getting first.

unknown flag: --show-all Failed to communicate with heketi service._
The fix
This can be fixed by removing the '--show-all' in line: https://github.com/gluster/gluster-kubernetes/blob/7246eb4053c8c5336e4da68d86b76124d435eb3e/deploy/gk-deploy#L924
