 The runner is the application that runs a job from a GitHub Actions workflow. It is used by GitHub Actions in the [hosted virtual environments](https://github.com/actions/virtual-environments), or you can [self-host the runner](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/about-self-hosted-runners) in your own environment.

-**Date**: 2021-06-10
-
-**Status**: Accepted
-
-## Context
-
-We released [composite run steps](https://github.com/actions/runner/pull/554) last year which started our journey of reusing steps across different workflow files. To continue that journey, we want to expand composite run steps into composite actions.
-
-We want to support the `uses` steps from workflows in composite actions, including:
-  - Container actions
-  - Javascript actions
-  - Other Composite actions (up to a limit of course!)
-  - The pre and post steps these actions can generate
-
-## Guiding Principles
-
-- Composite Actions should function as a single step or action, no matter how many steps it is composed of or how many levels of recursion it has
-  - In the future we may add a configurable option to make this no longer the case
-- A workflow author should not need to understand the inner workings of a composite action in order to use it
-- Composite actions should leverage inputs to get values they need, they will not have full access to the `context` objects. The secrets context will **not** be available to composite actions, users will need to pass these values in as an input.
-- Other Actions should **just work** inside a composite action, without any code changes
-
-## Decisions
-
-### Composite Recursion Limit
-
-- We will start with supporting a recursion limit of `10` composite actions deep
-- We are free to bump this limit in the future, the code will be written to just require updating a variable. If the graph evaluates beyond the recursion limit, the job will fail in the pre-job phase (The `Set up job` step).
-- A composite actions interface is its inputs and outputs, nothing else is carried over when invoking recursively.
-
-### Pre/Post Steps in nested Actions
-
-- We do not plan on adding the ability to configure a customizable pre or post step for composite actions at this time. However, we will execute the pre and post steps of any actions referenced in a composite action.
-- Composite actions will generate a single pre-step and post-step for the entire composite action, even if there are multiple pre-steps and post-steps in the referenced actions.
-  - These steps will execute following the same ordering rules we have today, first to run has their pre step run first and their post step run last.
-  - For example, if you had a composite action with two pre steps and two posts steps:
-
-  ```
-  - uses: action1
-  - uses: composite1
-  - uses: action2
-  ```
-
-  The order of execution would be:
-
-  ```
-  - prestep-action1
-  - prestep-composite1
-    - prestep-composite1-first-action-referenced
-    - prestep-composite1-second-action-referenced
-  - prestep-action2
-  - the job steps
-  - poststep-action2
-  - poststep-composite1
-    - poststep-composite1-the-second-action-referenced
-    - poststep-composite1-first-action-referenced
-  - poststep-action1
-  ```
-
-#### Set-state
-
-- While the composite action has an individual combined pre/post action, the `set-state` command will not be shared.
-- If the `set-state` command is used during a composite step, only the action that originally called `set-state` will have access to the env variable during the post run step.
-  - This prevents multiple actions that set the same state from interfering with the execution of another action's post step.
-
-### Resolve Action Endpoint changes
-
-- The resolve actions endpoint will now validate policy to ensure that the given workflow run has access to download that action.
-  - Older GHES/GHAE customers with newer runners will be locked out of composite uses steps until they upgrade their instance.
-
-### Local actions
-- Local actions will expand the tree, perform policy checks, and download actions Just in Time when the step is running.
-- Like current local actions, we will not support presteps. If an action is running local, by the time we know that, the time to run presteps have already passed.
-
-### If, continue-on-error, timeout-minutes - Not being considered at this time
-
-- `if`, `continue-on-error`, `timeout-minutes` could be supported in composite run/uses steps. These values were not originally supported in our composite run steps implementation.
-  - Browsing the community forums and runner repo, there hasn't been a lot of noise asking for these features, so we will hold off on them.
-- These values passed as input into the composite action will **not** be carried over as input into the individual steps the composite action runs.
-
-### Defaults - Not being considered at this time
-
-- In actions, we have the idea of [defaults](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#defaultsrun) , which allow you to specify a shell and working directory in one location, rather then on each step.
-- However, `shell` is currently required in composite run steps
-  - In regular run steps, it is optional, and defaults to a different value based on the OS.
-- We want to prioritize the right experience for the consumer, and make the action author continue to explicitly set these values. We can consider improving this experience in the future.
-
-## Consequences
-
-- Workflows are now more reusable across multiple workflow files
-- Composite actions implement most of the existing workflow run steps, with room to expand these in the future
-- Feature flags will control this rollout

-# ADR 1438: Support Conditionals In Composite Actions
-
-**Date**: 2021-10-13
-
-**Status**: Accepted
-
-## Context
-
-We recently shipped composite actions, which allows you to reuse individual steps inside an action. 
-However, one of the [most requested features](https://github.com/actions/runner/issues/834) has been a way to support the `if` keyword.
-
-### Goals
-- We want to keep consistent with current behavior
-- We want to support conditionals via the `if` keyword
-- Our built in functions like `success` should be implementable without calling them, for example you can do `job.status == success` rather then `success()` currently.
-
-### How does composite currently work?
-
-Currently, we have limited conditional support in composite actions for `pre` and `post` steps. 
-These are based on the `job status`, and support keywords like `always()`, `failed()`, `success()` and `cancelled()`. 
-However, generic or main steps do **not** support conditionals.
-
-By default, in a regular workflow, a step runs on the `success()` condition. Which looks at the **job** **status**, sees if it is successful and runs.
-
-By default, in a composite action, main steps run until a single step fails in that composite action, then the composite action is halted early. It does **not** care about the job status.
-Pre, and post steps in composite actions use the job status to determine if they should run.
-
-### How do we go forward?
-
-Well, if we think about what composite actions are currently doing when invoking main steps, they are checking if the current composite action is successful. 
-Lets formalize that concept into a "real" idea.
-
-- We will add an `action_status` field to the github context to mimic the [job's context status](https://docs.github.com/en/actions/learn-github-actions/contexts#job-context).
-  - We have an existing concept that does this `action_path` which is only set for composite actions on the github context.
-- In a composite action during a main step, the `success()` function will check if `action_status == success`, rather then `job_status == success`. Failure will work the same way. 
-  - Pre and post steps in composite actions will not change, they will continue to check the job status.
-
-
-### Nested Scenario
-For nested composite actions, we will follow the existing behavior, you only care about your current composite action, not any parents. 
-For example, lets imagine a scenario with a simple nested composite action
-
-```
-- Job
-  - Regular Step
-  - Composite Action
-    - runs: exit 1
-    - if: always()
-      uses: A child composite action
-        - if: success()
-          runs: echo "this should print"
-        - runs: echo "this should also print"
-    - if: success()
-      runs: echo "this will not print as the current composite action has failed already"
-      
-```
-The child composite actions steps should run in this example, the child composite action has not yet failed, so it should run all steps until a step fails. This is consistent with how a composite action currently works in production if the main job fails but a composite action is invoked with `if:always()` or `if: failure()`
-
-### Other options explored
-We could add the `current_step_status` to the job context rather then `__status` to the steps context, however this comes with two major downsides:
-- We need to support the field for every type of step, because its non trivial to remove a field from the job context once it has been added (its readonly)
-  - For all actions besides composite it would only every be `success`
-  - Its weird to have a `current_step` value on the job context
-- We also explored a `__status` on the steps context.
-  - The `__` is required to prevent us from colliding with a step with id: status
-  - This felt wrong because the naming was not smooth, and did not fit into current conventions.
-
-### Consequences
-- github context has a new field for the status of the current composite action.
-- We support conditional's in composite actions
-- We keep the existing behavior for all users, but allow them to expand that functionality.

-### Troubleshooting: Why can't I configure a runner?
-
-If you are having trouble connecting, try these steps:
-
-1. Validate you can reach our endpoints from your web browser. If not, double check your local network connection
-    - For hosted Github:
-      - https://api.github.com/
-      - https://vstoken.actions.githubusercontent.com/_apis/health
-      - https://pipelines.actions.githubusercontent.com/_apis/health
-    - For GHES/GHAE
-      - https://myGHES.com/_services/vstoken/_apis/health
-      - https://myGHES.com/_services/pipelines/_apis/health
-      - https://myGHES.com/api/v3
-2. Validate you can reach those endpoints in powershell core
-    - The runner runs on .net core, lets validate the local settings for that stack
-    - Open up `pwsh`
-    - Run the command using the urls above `Invoke-WebRequest {url}`
-3. If not, get a packet trace using a tool like wireshark and start looking at the TLS handshake.
-    - If you see a Client Hello followed by a Server RST:
-      - You may need to configure your TLS settings to use the correct version
-        - You should support TLS version 1.2 or later
-      - You may need to configure your TLS settings to have up to date cipher suites, this may be solved by system updates and patches.
-        - Most notably, on windows server 2012 make sure [the tls cipher suite update](https://support.microsoft.com/en-us/topic/update-adds-new-tls-cipher-suites-and-changes-cipher-suite-priorities-in-windows-8-1-and-windows-server-2012-r2-8e395e43-c8ef-27d8-b60c-0fc57d526d94) is installed
-      - Your firewall, proxy or network configuration may be blocking the connection
-      - You will want to reach out to whoever is in charge of your network with these pcap files to further troubleshoot
-    - If you see a failure later in the handshake:
-      - Try the fix in the [SSLCert Fix](./sslcert.md)
