To build this tool from a checked out copy of the repository, run:
make
This will produce an executable named opfcli-<os>-<arch>
(for
example, opfcli-linux-amd64
).
A command line tool for Operate First GitOps.
Use opfcli to interact with an Operate First style Kubernetes
configuration repository.
Usage:
opfcli [command]
Available Commands:
create-group Create a group
create-project Onboard a new project into Operate First
enable-monitoring Enable monitoring for a Kubernetes namespace
grant-access Grant a group access to a namespace
help Help about any command
onboard Creates Groups, Namespaces, and Roles for a new Operate First project
Flags:
-a, --app-name string application name (default "cluster-scope")
-f, --config string configuration file
-h, --help help for opfcli
-R, --repodir string path to opf repository
Create a group.
Create the group resource and associated kustomization file
Usage:
opfcli create-group group [flags]
Flags:
-h, --help help for create-project
-d, --display-name short team description for easy identification of project
-n do not set a limitrange on this project
-u, --users comma seperated list of users to add to the group
Onboard a new project into Operate First.
- Register a new group
- Register a new namespace with appropriate role bindings for your group
Usage:
opfcli create-project projectName projectOwner [flags]
Flags:
-d, --description string Team description
-h, --help help for create-project
-n, --no-limitrange Do not set a limitrange on this project
-q, --quota string Set a quota on this project
Global Flags:
-a, --app-name string application name (default "cluster-scope")
-f, --config-file string configuration file
-r, --repo-dir string path to opf repository
Enable monitoring for a Kubernetes namespace.
This will add a RoleBinding to the target namespace that permits
Prometheus to access certain metrics about pods, services, etc.
Usage:
opfcli enable-monitoring namespace [flags]
Flags:
-h, --help help for enable-monitoring
Grant a group access to a namespace.
Grant a group access to a namespace with the specifed role
(admin, edit, or view).
Usage:
opfcli grant-access namespace group role [flags]
Flags:
-h, --help help for grant-access
Onboard everything necessary for a new application into the Operate-First environment.
The onboard command expects an onboarding configuration file. These are the necessary and optional paramaters that make up the onboarding configuration file.
Necessary parameters:
team_name
= name of the group looking to be onboarded<namespaces[i]>.name
= the name of the namespace(s) for you project (defined per namespace)project_description
= short summary of your projecttarget_cluster
= name of the cluster to onboard toenv
= name of the environment in which thetarget_cluster
lives
Optional parameters:
<namespaces[i]>.quota
= Namespace Quota<namespaces[i]>.custom_quota
= a customizeable resource quota to be applied to its namespaceusers
= users to be given access to the project when onboarding
This is an example of a valid configuration file using every option. Below each component will be discussed.
env: MOC
namespaces:
- enable_monitoring: false
name: testproject
quota: testquota
disable_limit_range: false
project_display_name: testprojectdisplayname
custom_quota:
limits.cpu: '28'
requests.cpu: '28'
limits.memory: 32Gi
requests.memory: 32Gi
requests.storage: 100Gi
count/objectbucketclaims.objectbucket.io: 1
project_description: This is the configuration for a sample project / app to onboard
target_cluster: Smaug
team_name: testgroup
users:
- testing_gh_handle_1
- testing_gh_handle_2
Values for target_cluster
can be obtained by running:
kustomize build https://github.com/operate-first/apps/acm/overlays/moc/infra/managedclusters?ref=master | yq e -N '.metadata.name' -
Similarly, values for env
can be obtained by running:
curl -sX GET https://api.github.com/repos/operate-first/apps/contents/argocd/overlays/moc-infra/applications/envs | yq e '.[].name' -
- Requires: yq
NOTE: the opfcli
is made for use in operate-first/apps
which is why these urls are either curl
ed or used in kustomize build.
If you cannot install kustomize
and or yq
, our last known options for env
and target_cluster
are as follows:
- env:

- target_cluster:

- target_cluster:

- target_cluster:

- target_cluster:

quota
s: Quota's are optional values that refer to names of common ResourceQuotas inoperate-first/apps
. They limit the resources able to be used in a specific namespace. -
custom_quota
s: Custom quotas are optional configurations for a customResourceQuota
to be used in a namespace. The values of a custom quota reflect those of our resourcequotas defined per namespace in operate-first/apps see example.- If a valid
quota
is selected but acustom_quota
is also defined in your configuration file, it will default to creating the namespace using thecustom_quota
. - All values are optional in a
custom_quota
. custom_quota
options:[limits.cpu, requests.cpu, limits.memory, requests.memroy, requests.storage, count/objectbucketclaims.objectbucket.io]
- If a valid
-
disable_limit_range
: All requests to create and modify resources in Openshift are evaluated against eachLimitRange
object in the project. If the resource violates any of the enumerated constraints, the resource is rejected. Settingdisable_limit_range
totrue
, creates a namespace without the operate-first default limit range. -
display_project_name
: display-names in openshift are user-defined strings which provide an alternative, more human-readable way to refer to a namespace. For more information on this checkout the openshift docs on projects.
GitHub handles that will be used to authenticate OCP clusters via GitHub. These GitHub usernames are converted to OCP users and are also used to extend permissions via Openshift RBAC.
Usage:
opfcli onboard <file-path>
Flags:
-d, --display-name provide a shorter name to use to refer to the project in openshift
-n, --no-limitrange Do not set a resource limitrange on this project
Use "opfcli [command] --help" for more information about a command.
The opfcli
command will look for a configuration file .opfcli.yaml
in two places:
-
It first checks in the top level of the current git repository. If you are running the
opfcli
command outside of a git repository it will instead check the current directory. -
If it doesn't find a local configuration file, it will look for
~/.opfcli.yaml
.
Use the OPF_LOGLEVEL
environment variable to set logging verbosity.
The default is 1
(informational), but you can also set it to 0
(warnings only) or 2
(or greater), which enables debug output.
app-name
-- sets the name of the directory containing your YAML resources. This defaults tocluster-scope
.
