 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.

+## Common Network Related Issues
+
+### Common things that can cause the runner to not working properly
+
+- Bug in the runner or the dotnet framework that causes actions runner can't make Http request in a certain network environment.
+
+- Proxy/Firewall block certain HTTP method, like it block all POST and PUT calls which the runner will use to upload logs.
+
+- Proxy/Firewall only allows requests with certain user-agent to pass through and the actions runner user-agent is not in the allow list.
+
+- Proxy try to decrypt and exam HTTPS traffic for security purpose but cause the actions-runner to fail to finish SSL handshake due to the lack of trusting proxy's CA.
+
+- Proxy try to modify the HTTPS request (like add or change some http headers) and causes the request become incompatible with the Actions Service (ASP.NetCore), Ex: [Nginx](https://github.com/dotnet/aspnetcore/issues/17081)
+
+- Firewall rules that block action runner from accessing certain hosts, ex: `*.github.com`, `*.actions.githubusercontent.com`, etc.
+
+
+### Identify and solve these problems
+
+The key is to figure out where is the problem, the network environment, or the actions runner?
+
+Use a 3rd party tool to make the same requests as the runner did would be a good start point.
+
+- Use `nslookup` to check DNS
+- Use `ping` to check Ping
+- Use `traceroute`, `tracepath`, or `tracert` to check the network route between the runner and the Actions service 
+- Use `curl -v` to check the network stack, good for verifying default certificate/proxy settings.
+- Use `Invoke-WebRequest` from `pwsh` (`PowerShell Core`) to check the dotnet network stack, good for verifying bugs in the dotnet framework.
+
+If the 3rd party tool is also experiencing the same error as the runner does, then you might want to contact your network administrator for help.

+## SSL Certificate Related Issues
+
+You might run into an SSL certificate error when your GitHub Enterprise Server is using a self-signed SSL server certificate or a web proxy within your network is decrypting HTTPS traffic for a security audit.
+
+As long as your certificate is generated properly, most of the issues should be fixed after your trust the certificate properly on the runner machine.
+
+> Different OS might have extra requirements on SSL certificate,
+> Ex: macOS requires `ExtendedKeyUsage` https://support.apple.com/en-us/HT210176
+
+### Don't skip SSL cert validation
+
+> !!! DO NOT SKIP SSL CERT VALIDATION !!!  
+> !!! IT IS A BAD SECURITY PRACTICE !!!  
+
+### Download SSL certificate chain 
+
+Depends on how your SSL server certificate gets configured, you might need to download the whole certificate chain from a machine that has trusted the SSL certificate's CA.
+
+- Approach 1: Download certificate chain using a browser (Chrome, Firefox, IT), you can google for more example, [here is what I found](https://medium.com/@menakajain/export-download-ssl-certificate-from-server-site-url-bcfc41ea46a2)
+
+- Approach 2: Download certificate chain using OpenSSL, you can google for more example, [here is what I found](https://superuser.com/a/176721)
+
+- Approach 3: Ask your network administrator or the owner of the CA certificate to send you a copy of it
+
+### Trust CA certificate for the Runner
+
+The actions runner is a dotnet core application which will follow how dotnet load SSL CA certificates on each OS.
+
+You can get full details documentation at [here](https://docs.microsoft.com/en-us/dotnet/standard/security/cross-platform-cryptography#x509store)
+
+In short: 
+- Windows: Load from Windows certificate store.
+- Linux: Load from OpenSSL CA cert bundle.
+- macOS: Load from macOS KeyChain.
+
+To let the runner trusts your CA certificate, you will need to:
+1. Save your SSL certificate chain which includes the root CA and all intermediate CAs into a `.pem` file.
+2. Use `OpenSSL` to convert `.pem` file to a proper format for different OS, here is some [doc with sample commands](https://www.sslshopper.com/ssl-converter.html)
+3. Trust CA on different OS:
+    - Windows: https://docs.microsoft.com/en-us/skype-sdk/sdn/articles/installing-the-trusted-root-certificate
+    - macOS: ![trust ca cert](./../res/macOStrustCA.gif)
+    - Linux: Refer to the distribution documentation
+      1. RedHat: https://www.redhat.com/sysadmin/ca-certificates-cli
+      2. Ubuntu: http://manpages.ubuntu.com/manpages/focal/man8/update-ca-certificates.8.html
+      3. Google search: "trust ca certificate on [linux distribution]"
+      4. If all approaches failed, set environment variable `SSL_CERT_FILE` to the CA bundle `.pem` file we get. 
+    > To verity cert gets installed properly on Linux, you can try use `curl -v https://sitewithsslissue.com` and `pwsh -Command \"Invoke-WebRequest -Uri https://sitewithsslissue.com\"`
+
+### Trust CA certificate for Git CLI
+
+Git uses various CA bundle file depends on your operation system.
+- Git packaged the CA bundle file within the Git installation on Windows 
+- Git use OpenSSL certificate CA bundle file on Linux and macOS
+
+You can check where Git check CA file by running:
+```bash
+export GIT_CURL_VERBOSE=1
+git ls-remote https://github.com/actions/runner HEAD
+```
+
+You should see something like:
+```
+* Couldn't find host github.com in the .netrc file; using defaults
+*   Trying 140.82.114.4...
+* TCP_NODELAY set
+* Connected to github.com (140.82.114.4) port 443 (#0)
+* ALPN, offering h2
+* ALPN, offering http/1.1
+* successfully set certificate verify locations:
+*   CAfile: /etc/ssl/cert.pem
+  CApath: none
+* SSL connection using TLSv1.2 / ECDHE-RSA-AES128-GCM-SHA256
+```
+This tells me `/etc/ssl/cert.pem` is where it read trusted CA certificates.
+
+To let Git trusts your CA certificate, you will need to:
+1. Save your SSL certificate chain which includes the root CA and all intermediate CAs into a `.pem` file.
+2. Set `http.sslCAInfo` Git config or `GIT_SSL_CAINFO` environment variable to the full path of the `.pem` file [Git Doc](https://git-scm.com/docs/git-config#Documentation/git-config.txt-httpsslCAInfo)
+> I would recommend using `http.sslCAInfo` since it can be scope to certain hosts that need the extra trusted CA.  
+> Ex: `git config --global http.https://myghes.com/.sslCAInfo /extra/ca/cert.pem`  
+> This will make Git use the `/extra/ca/cert.pem` only when communicates with `https://myghes.com` and keep using the default CA bundle with others.
+
+### Trust CA certificate for Node.js
+
+Node.js has compiled a snapshot of the Mozilla CA store that is fixed at each version of Node.js' release time.
+
+To let Node.js trusts your CA certificate, you will need to:
+1. Save your SSL certificate chain which includes the root CA and all intermediate CAs into a `.pem` file.
+2. Set environment variable `NODE_EXTRA_CA_CERTS` which point to the file. ex: `export NODE_EXTRA_CA_CERTS=/full/path/to/cacert.pem` or `set NODE_EXTRA_CA_CERTS=C:\full\path\to\cacert.pem`

Robin Neatherway	66727f76c8	Add on: pull_request trigger to CodeQL workflow (#907 ) From February 2021, in order to provide feedback on pull requests, Code Scanning workflows must be configured with both `push` and `pull_request` triggers. This is because Code Scanning compares the results from a pull request against the results for the base branch to tell you only what has changed between the two. Early in the beta period we supported displaying results on pull requests for workflows with only `push` triggers, but have discontinued support as this proved to be less robust. See https://docs.github.com/en/free-pro-team@latest/github/finding-security-vulnerabilities-and-errors-in-your-code/configuring-code-scanning#scanning-pull-requests for more information on how best to configure your Code Scanning workflows.	2021-01-14 13:26:37 -05:00
