Slack Guidelines

These are the policies, procedures, and escalation mechanisms for the Slack platform, such as requesting channels, tokens, and how to report inappropriate content.

Slack serves as the main communication platform for the Kubernetes community outside of the mailing lists. It’s important that conversations stay on topic in each channel, and that everyone abides by the Code of Conduct. There are over 150,000 members who should all expect to have a positive experience. You are a part of building and keeping a positive community.

Chat is searchable and public. It’s best not to make comments that you would not say on a video recording or in another public space. Please be courteous to others.

Code of Conduct

Kubernetes adheres to the Kubernetes Code of Conduct throughout the project, and includes all communication mediums.


Slack Admins will have listed that they are a Slack admin in their Slack profile, along with their specific timezone.

To connect: please reach out in the #slack-admins channel, mention an admin directly in the #slack-admins channel when you have a question, or DM (direct message) one privately.

General Communication Guidelines

Workspace Channel History

The Kubernetes Slack Workspace is archived and made available when the administrators have time. There is no explicit interval.

DM (Direct Message) Conversations

Please do not engage in proprietary company specific conversations in the Kubernetes Slack instance. This workspace is meant for conversations related to Kubernetes open source topics and community. Proprietary conversations should occur in your company Slack and/or communication platforms. As with all communication, please be mindful of appropriateness, professionalism, and applicability to the Kubernetes community.

Specific Channel Rules

Some channels have specific rules or guidelines. If they do, they will be listed in the purpose or pinned docs of that channel.

  • #kubernetes-contributors - Questions and discourse around upstream contributions and development to kubernetes.
  • #kubernetes-careers - Job openings for positions working with/on/around Kubernetes. Postings must include:
    • A link to the posting or job description.
    • The business name that will employ the Kubernetes hire.
    • The location of the role or if remote is OK.
  • #surveys - Cloud native community wide surveys. Posts must be ecosystem related.

Escalating and/or Reporting a Problem

The Kubernetes Slack has an integrated tool for reporting issues. It may be accessed by clicking on “More actions”, the “” to the right of a message, and selecting Report message.

This will open a new dialog prompt where you may describe the problem. When done, it will send the reported message and your comments to BOTH the Slack admins and Code of Conduct Committee (CoCC).

A Slack admin or CoCC member will work to resolve the issue or reach out for more information.

If the issue has not been responded to in a timely manner, Join the #slack-admins channel and alert the admins to the current issue. Many Slack admins watch the channel and should respond to you shortly.

As a last resort, or if the issue is private, contact one of the admins in the closest timezone via DM directly and describe the situation. If the issue can be documented, please take a screenshot to include in your message.

What if you have a problem with an admin?

Send a DM to another listed admin and describe the situation. If it’s a code of conduct issue, please send an email to and describe the situation.

Should you have a channel on the Kubernetes Slack?

The primary purpose of the Kubernetes slack is for the coordination of the Kubernetes project. However it is useful for developers and users to have a strong ecosystem of channels for related things. Here are some guidelines for determining if you should request a channel:

  • The channel MUST be Kubernetes related in some way.
    • Related cloud native projects might be more appropriate on the CNCF Slack.
  • The project MUST be open source.
    • Open Source a project BEFORE requesting a channel. We cannot accommodate every organization’s open sourcing launch plans.
    • The purpose of Slack is to organize an existing community, not seed new ones.
    • Moderators look at contributor activity, adoption and community consensus around a project, otherwise Slack becomes a vehicle for promotion instead of promulgation.
    • Establishment and maintenance of a Slack channel should be an inflection point in a project’s adoption.
    • Requesting a channel means maintaining it on behalf of the project filing the issue. You will be expected to participate and foster a healthy discourse.
    • External projects (ones not owned by a Kubernetes SIG) may have a maximum of two channels, usually #project or #project-users, and #project-dev.
    • A second channel for a specific project will not be approved until the first channel demonstrates significant traffic.
  • Channels around commercial services built on OSS projects are allowed.
    • Users love the value of being able to collaborate around various services.
    • Keep it classy, on the Kubernetes Slack we’re all on the same team.
  • The channel MUST be public.
    • In order to ensure all channels adhere to our Code of Conduct, we heavily restrict private channels.
    • If you need private discussion areas for security-sensitive topics, a project-specific Slack or the CNCF Slack may be a better fit.
  • Ask in #slack-admins or file an issue if you’re unsure It never hurts to ask.

Requesting a Channel

Channels and User Groups are managed by Tempelis, a tool that enables external management of Slack.

To add a channel, open a Pull Request (PR) updating the slack-config.

  • Add the channel to ‘channels.yaml’ following the Channel Documentation
    • Channel names must be 21 characters or less in length, limited by Slack design.
    • Channels must not share the same name with a Slack user or user group.
    • Typical channel naming conventions follow:
      • #kubernetes-foo
      • #sig-foo
      • #meetup-foo
      • #location-user
      • #projectname
  • In the PR comments, include some details regarding the purpose of the Channel.
    • Channels should be dedicated to SIGs or WGs, sub-projects, community topics, or related Kubernetes programs/projects.
    • Linking to resources such as the PR adding the subproject will speed in the validation and processing of the channel creation request.
    • Channels are NOT
      • Company specific; cloud providers are ok with product names as the channel. Discourse will be about Kubernetes-related topics and not proprietary information of the provider.
      • Private channels with the exception of: code of conduct matters, mentoring, security/vulnerabilities, github management, or steering committee.
    • Special accommodations will be made where necessary.

After you submit your request the Slack Admins will review and follow-up with any questions in the PR itself. There are two approvals needed. /lgtm and /approve. Once one moderator give the /lgtm, a hold will be placed on the PR using /hold. This hold will remain in place until one or more moderators reviews and add the /approve command as well as /hold cancel, which will remove the hold on the PR. Once it is signed off and merged, the channel will be created.

For further information, see the Slack Config Documentation.

Delegating Channel Ownership

Channel management can be delegated to other groups, enabling SIG leads or other members to govern certain sets of channels. This bypasses the need for a Slack Admins to sign-off on all requests and passes the responsibility to the most relevant group.

To delegate channel ownership - Open a Pull Request (PR) updating the slack-config.

  • Create a sub-directory under the slack-config for your sig or group.
  • Update restrictions.yaml with an entry targeting yaml config files in the sub-directory you created along with one or more regular expressions that match the channel names that should be delegated.
    • Example Restrictions Entry:
      - path: "sig-foo/*.yaml"          # path to channel config
        - "^kubernetes-foo-[a-z]{1,3}$" # channel regexp - example match: kubernetes-foo-bar
        - "^foo-[a-zA-Z]+$"             # channel regexp - example match: foo-awesomechannel
  • Create an OWNERS file in the sub-directory adding the appropriate reviewers and approvers for the desired channels.
  • In the directory create one or more channel configs following the Channel Documentation
    • Example Channel Config:
      - name: kubernetes-foo-bar # regexp: "^kubernetes-foo-[a-z]{1,3}$"
      - name: foo-users          # regexp: "^foo-[a-zA-Z]+$"
      - name: foo-dev            # regexp: "^foo-[a-zA-Z]+$"

After you submit your PR and the Slack Admins sign off on the update, it will be merged and the group will be able to fully self-manage their own channels.

For further information, see the Slack Config Documentation.

Requesting a User Group

Channels and User Groups are managed by Tempelis, a tool that enables external management of Slack.

To add a User Group, open a Pull Request (PR) updating the slack-config.

  • Add the users to users.yaml. NOTE: This must be a mapping of their GitHub ID to their Slack Member ID.
  • To get a person’s Slack Member ID, view their profile. Then click on the “” and select Copy member ID. It will be a 9 character string of uppercase letters and numbers (example: U1H63D8SZ).
  • Update usergroups.yaml Follow the guidelines for creating a User Group in the Slack Config User Group Documentation.
  • In the PR comments, include details on the User Group and /cc the members you are adding so that they may sign off and accept being added to the group.

After you submit your request, the Slack Admins will review and follow-up with any questions in the PR itself. Once it is signed off by the members being added and the Slack Admins, it will be merged, and the User Group will be created.

For further information, see the Slack Config Documentation.

Requesting a Bot, Token, or Webhook


Bots, tokens, and webhooks are reviewed on a case-by-case basis with most requests being rejected due to security, privacy, and usability concerns. Bots and the like tend to make a lot of noise in channels. The Kubernetes Slack instance has over 145,000 members and it is the role of the Slack admins to ensure everyone has a great experience.

Typically approved requests include: GitHub, CNCF requests, or other tools/platforms used to aid in the management of Slack itself.

  • Create a GitHub Issue using the Slack Request template.
  • In the description, describe the request, its intended purpose and benefit to the community. Supplying links to supporting content such as a document outlining what OAuth scopes that are requested and why are STRONGLY ENCOURAGED.

After you submit your request, the Slack admins will review and follow-up with any questions in the issue. If consensus can be reached among the admins, the request will be approved and follow-up communication on implementation will be discussed in Slack itself.


Admin Expectations and Guidelines

Admins should adhere to the general Kubernetes project moderation guidelines.

Additionally, admins should ensure they have 2-factor auth enabled for their account and mention they are a Slack admin in the “What I do” portion of their profile. This message should also include the time zone they are representing.

Be mindful of how you handle communication during stressful interactions. Administrators act as direct representatives of the community, and need to maintain a very high level of professionalism at all times. If you feel too involved in the situation to maintain impartiality or professionalism, that’s a great time to enlist the help of another admin.

Try to take any situations that involve upset or angry members to DM or video chat. Please document these interactions for other Slack admins to review.

Content will be removed if it violates code of conduct or is a sales pitch. Admins will take a screenshot of such behavior in order to document the situation. The community takes such violations extremely seriously, and the admins are empowered to handle it swiftly.

Sending Messages to the Channel

@all, @here and @channel should be used rarely. Members will receive notifications from these commands. Remember Kubernetes is a global project—please be kind.

Processing Slack Requests

Admins are tasked with processing requests for channels and other things such as bots, tokens or webhooks. Please see the processes outlined below.

Processing Channel Requests

Channel requests should be reviewed for their relation and relevance to the Kubernetes community. Typically channels should be dedicated to SIGs, WGs, sub-projects, community topics, and other things related to Kubernetes programs and projects.

For Kubernetes project centric requests, validate them against the sig-list, or request a link to a related issue/PR, or mailing list discussion for the requested Channel.

Small external projects are encouraged to use the channel of the SIG or WG most relevant to them. Other things such as programming language-specific channels are discouraged and should in turn be steered to #kubernetes-client or communication avenues commonly used by their specific language.

In general, use your best judgment.

Once two Slack admins have reviewed and agreed to sponsor the channel, they will sign off on the Channel Request PR. Once merged, the channel will be created.

Channels managed by Tempelis will automatically have default messages pinned. For any manually-provisioned channels, such as private channels, add the below message and pin it.

This channel abides to the Kubernetes Code of Conduct -
Contact or an admin in the #slack-admins channel if there
is a problem.

Processing User Group Requests

User Group requests should be reviewed for their relation and relevance to the Kubernetes community along with their importance to the requesting group. They are a useful alias, but can also easily be spammed or abused.

Before signing off on a User Group PR request, ensure all members of the User Group have signed off acknowledging they will be added to the group.

After all the User Group members have accepted being added to the group and two Slack Admins have signed off on the request, the PR will be merged. Once merged, the User Group will be created.

Processing Bot, Token, or Webhook Requests

Requests should first be evaluated for their relevance to the project. Typically approved requests are related to: GitHub, the CNCF, or other tools and platforms used to aid in the management of Slack. Requests outside of this scope should be heavily scrutinized and reviewed for ANY potential security, privacy, or usability concerns.

It is best to err on the side of not allowing a bot, token, or webhook request rather than allowing one.

If the admins come to consensus and agree to the request, an admin should assign the issue to themselves and reach out to the request contact regarding next steps.

Inactivating Accounts

For the reasons listed below, admins may inactivate individual Slack accounts. Due to Slack’s framework, it does not allow for an account to be banned or suspended in the traditional sense, merely inactivated. See Slack’s policy on inactivated accounts for more information.

Reasons to inactivate an account

  • Spreading spam content in DMs and/or channels.
  • Not adhering to the code of conduct set forth in DMs and/or channels.
  • Overtly selling products, related or unrelated to Kubernetes.


To inactivate a user, and optionally remove their content (spam):

  • First, double check you have the correct user by verifying their Slack Member ID.
  • Spammers may try and fake or assume the identity of another user.

Once verified, find a message from the offending user. Then select More actions, the “” to the right of a message from the offending user. Then select Report message.

This will open a contextually-aware prompt only available to Slack Admins with the options to deactivate the user and remove all content from them over the past “X” minutes/hours.

Report any actions taken to the other slack admins, and if needed the Code of Conduct Committee.
