Limitations on Grant Scope 111 | 112 | The licenses granted in this Section 2 are the only rights granted under 113 | this License. No additional rights or licenses will be implied from the 114 | distribution or licensing of Covered Software under this License. 115 | Notwithstanding Section 2.1(b) above, no patent license is granted by a 116 | Contributor: 117 | 118 | (a) for any code that a Contributor has removed from Covered Software; 119 | or 120 | 121 | (b) for infringements caused by: (i) Your and any other third party's 122 | modifications of Covered Software, or (ii) the combination of its 123 | Contributions with other software (except as part of its Contributor 124 | Version); or 125 | 126 | (c) under Patent Claims infringed by Covered Software in the absence of 127 | its Contributions. 128 | 129 | This License does not grant any rights in the trademarks, service marks, 130 | or logos of any Contributor (except as may be necessary to comply with 131 | the notice requirements in Section 3.4). 132 | 133 | 2.4. Subsequent Licenses 134 | 135 | No Contributor makes additional grants as a result of Your choice to 136 | distribute the Covered Software under a subsequent version of this 137 | License (see Section 10.2) or under the terms of a Secondary License (if 138 | permitted under the terms of Section 3.3). 139 | 140 | 2.5.

Fair Use 147 | 148 | This License is not intended to limit any rights You have under 149 | applicable copyright doctrines of fair use, fair dealing, or other 150 | equivalents. 151 | 152 | 2.7. Conditions 153 | 154 | Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted 155 | in Section 2.1. 156 | 157 | 3. Responsibilities 158 | ------------------- 159 | 160 | 3.1. Distribution of Source Form 161 | 162 | All distribution of Covered Software in Source Code Form, including any 163 | Modifications that You create or to which You contribute, must be under 164 | the terms of this License. You must inform recipients that the Source 165 | Code Form of the Covered Software is governed by the terms of this 166 | License, and how they can obtain a copy of this License. You may not 167 | attempt to alter or restrict the recipients' rights in the Source Code 168 | Form. 169 | 170 | 3.2. Distribution of Executable Form 171 | 172 | If You distribute Covered Software in Executable Form then: 173 | 174 | (a) such Covered Software must also be made available in Source Code 175 | Form, as described in Section 3.1, and You must inform recipients of 176 | the Executable Form how they can obtain a copy of such Source Code 177 | Form by reasonable means in a timely manner, at a charge no more 178 | than the cost of distribution to the recipient; and 179 | 180 | (b) You may distribute such Executable Form under the terms of this 181 | License, or sublicense it under different terms, provided that the 182 | license for the Executable Form does not attempt to limit or alter 183 | the recipients' rights in the Source Code Form under this License. 184 | 185 | 3.3. Distribution of a Larger Work 186 | 187 | You may create and distribute a Larger Work under terms of Your choice, 188 | provided that You also comply with the requirements of this License for 189 | the Covered Software. If the Larger Work is a combination of Covered 190 | Software with a work governed by one or more Secondary Licenses, and the 191 | Covered Software is not Incompatible With Secondary Licenses, this 192 | License permits You to additionally distribute such Covered Software 193 | under the terms of such Secondary License(s), so that the recipient of 194 | the Larger Work may, at their option, further distribute the Covered 195 | Software under the terms of either this License or such Secondary 196 | License(s). 197 | 198 | 3.4. Notices 199 | 200 | You may not remove or alter the substance of any license notices 201 | (including copyright notices, patent notices, disclaimers of warranty, 202 | or limitations of liability) contained within the Source Code Form of 203 | the Covered Software, except that You may alter any license notices to 204 | the extent required to remedy known factual inaccuracies. 205 | 206 | 3.5. Application of Additional Terms 207 | 208 | You may choose to offer, and to charge a fee for, warranty, support, 209 | indemnity or liability obligations to one or more recipients of Covered 210 | Software. However, You may do so only on Your own behalf, and not on 211 | behalf of any Contributor. You must make it absolutely clear that any 212 | such warranty, support, indemnity, or liability obligation is offered by 213 | You alone, and You hereby agree to indemnify every Contributor for any 214 | liability incurred by such Contributor as a result of warranty, support, 215 | indemnity or liability terms You offer. You may include additional 216 | disclaimers of warranty and limitations of liability specific to any 217 | jurisdiction. 218 | 219 | 4. Inability to Comply Due to Statute or Regulation 220 | --------------------------------------------------- 221 | 222 | If it is impossible for You to comply with any of the terms of this 223 | License with respect to some or all of the Covered Software due to 224 | statute, judicial order, or regulation then You must: (a) comply with 225 | the terms of this License to the maximum extent possible; and (b) 226 | describe the limitations and the code they affect. Such description must 227 | be placed in a text file included with all distributions of the Covered 228 | Software under this License. Except to the extent prohibited by statute 229 | or regulation, such description must be sufficiently detailed for a 230 | recipient of ordinary skill to be able to understand it. 231 | 232 | 5. Termination 233 | -------------- 234 | 235 | 5.1. The rights granted under this License will terminate automatically 236 | if You fail to comply with any of its terms. However, if You become 237 | compliant, then the rights granted under this License from a particular 238 | Contributor are reinstated (a) provisionally, unless and until such 239 | Contributor explicitly and finally terminates Your grants, and (b) on an 240 | ongoing basis, if such Contributor fails to notify You of the 241 | non-compliance by some reasonable means prior to 60 days after You have 242 | come back into compliance. Moreover, Your grants from a particular 243 | Contributor are reinstated on an ongoing basis if such Contributor 244 | notifies You of the non-compliance by some reasonable means, this is the 245 | first time You have received notice of non-compliance with this License 246 | from such Contributor, and You become compliant prior to 30 days after 247 | Your receipt of the notice. 248 | 249 | 5.2. If You initiate litigation against any entity by asserting a patent 250 | infringement claim (excluding declaratory judgment actions, 251 | counter-claims, and cross-claims) alleging that a Contributor Version 252 | directly or indirectly infringes any patent, then the rights granted to 253 | You by any and all Contributors for the Covered Software under Section 254 | 2.1 of this License shall terminate. 255 | 256 | 5.3. In the event of termination under Sections 5.1 or 5.2 above, all 257 | end user license agreements (excluding distributors and resellers) which 258 | have been validly granted by You or Your distributors under this License 259 | prior to termination shall survive termination. 260 | 261 | ************************************************************************ 262 | * * 263 | * 6.

Miscellaneous 314 | ---------------- 315 | 316 | This License represents the complete agreement concerning the subject 317 | matter hereof. If any provision of this License is held to be 318 | unenforceable, such provision shall be reformed only to the extent 319 | necessary to make it enforceable. Any law or regulation which provides 320 | that the language of a contract shall be construed against the drafter 321 | shall not be used to construe this License against a Contributor. 322 | 323 | 10. Versions of the License 324 | --------------------------- 325 | 326 | 10.1. New Versions 327 | 328 | Mozilla Foundation is the license steward. Except as provided in Section 329 | 10.3, no one other than the license steward has the right to modify or 330 | publish new versions of this License. Each version will be given a 331 | distinguishing version number. 332 | 333 | 10.2. Effect of New Versions 334 | 335 | You may distribute the Covered Software under the terms of the version 336 | of the License under which You originally received the Covered Software, 337 | or under the terms of any subsequent version published by the license 338 | steward. 339 | 340 | 10.3. Modified Versions 341 | 342 | If you create software not governed by this License, and you want to 343 | create a new license for such software, you may create and use a 344 | modified version of this License if you rename the license and remove 345 | any references to the name of the license steward (except to note that 346 | such modified license differs from this License). 347 | 348 | 10.4. Distributing Source Code Form that is Incompatible With Secondary 349 | Licenses 350 | 351 | If You choose to distribute Source Code Form that is Incompatible With 352 | Secondary Licenses under the terms of this version of the License, the 353 | notice described in Exhibit B of this License must be attached. 354 | 355 | Exhibit A - Source Code Form License Notice 356 | ------------------------------------------- 357 | 358 | This Source Code Form is subject to the terms of the Mozilla Public 359 | License, v. 2.0. If a copy of the MPL was not distributed with this 360 | file, You can obtain one at http://mozilla.org/MPL/2.0/. 361 | 362 | If it is not possible or desirable to put the notice in a particular 363 | file, then You may include the notice in a location (such as a LICENSE 364 | file in a relevant directory) where a recipient would be likely to look 365 | for such a notice. 366 | 367 | You may add additional accurate notices of copyright ownership. 368 | 369 | Exhibit B - "Incompatible With Secondary Licenses" Notice 370 | --------------------------------------------------------- 371 | 372 | This Source Code Form is "Incompatible With Secondary Licenses", as 373 | defined by the Mozilla Public License, v. 2.0. 374 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # Twingate Connect Action 2 | A GitHub action for connecting to Twingate 3 | 4 | # Purpose 5 | This action is used to connect your Github workflows to private resources using Twingate [Services](https://docs.twingate.com/docs/services). Services in Twingate allow applying zero trust permissions to automated components of your network infrastructure. For more information, see our [product announcement](https://www.twingate.com/blog/ztna-infra-automation/). 6 | 7 | There are two common use cases: 8 | 1. Enabling access directly to private resources (eg. a database within a public cloud VPC) directly from your workflows without providing network-wide access. This allowed you to implement narrow, revocable access controls on any workflow. 9 | 2. Enable running GitHub workflows on public runners while having IP restrictions enabled. Supporting this requires routing traffic to `github.com` via a Twingate Connector. More information on how to use Twingate with IP whitelisting is available in our [documentation](https://docs.twingate.com/docs/saas-app-gating). 10 | 11 | # Usage 12 | ```yaml 13 | - uses: twingate/github-action@v1 14 | with: 15 | # The Twingate Service Key used to connect Twingate to the proper service 16 | # Learn more about [Twingate Services](https://docs.twingate.com/docs/services) 17 | # 18 | # Required 19 | service-key: ${{ secrets.EXAMPLE_SERVICE_KEY_SECRET_NAME }} 20 | ``` 21 | 22 | 23 | # Development 24 | 25 | To run action locally to debug you can use `act` (`brew install act`): 26 | ``` 27 | act -j test -s SERVICE_KEY --container-options "--cap-add NET_ADMIN --device /dev/net/tun" 28 | ``` 29 | 30 | It'll ask for `SERVICE_KEY` value interactively. 31 | 32 | # How To Release 33 | 34 | When releasing a new tag (`v1.4` for example) we also have to update the latest major version (`v1` in this case) 35 | to point to it. 36 | Example steps: 37 | 38 | ``` 39 | git tag v1.4 40 | git tag v1 -f 41 | git push origin v1 v1.4 -f 42 | gh release create v1.4 --generate-notes --verify-tag 43 | ``` 44 | 45 | # Known Limitations 46 | 47 | ## Actions running docker steps that require access to a Twingate Resource 48 | 49 | When running steps that run inside a docker container you'll need to override the container's `resolv.conf` 50 | to remove the `168.63.129.16` and search statement by running the following commands inside the container: 51 | 52 | ``` 53 | sed '/^nameserver 168.63.129.16$/d; /^search/d' /etc/resolv.conf > /tmp/resolv.conf && cat /tmp/resolv.conf > /etc/resolv.conf 54 | ``` 55 | 56 | ### Technical details 57 | 58 | The reason behind this is that on the VM running the Github workflow, Microsoft adds their own nameserver - `nameserver 168.63.129.16` - as part of internal logic to health Azure VMs (see details [here](https://learn.microsoft.com/en-us/azure/virtual-network/what-is-ip-address-168-63-129-16?tabs=windows)). 59 | 60 | The VM ad logic to only use that nameserver to resolve an internal Azure DNS: 61 | ``` 62 | $> resolvectl status 63 | 64 | Global 65 | Protocols: -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported 66 | resolv.conf mode: stub 67 | 68 | Link 2 (eth0) 69 | Current Scopes: DNS 70 | Protocols: +DefaultRoute -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported 71 | Current DNS Server: 168.63.129.16 72 | DNS Servers: 168.63.129.16 73 | DNS Domain: l2n2ciljpwpefjhhlkzs4uiluc.ex.internal.cloudapp.net 74 | 75 | Link 3 (docker0) 76 | Current Scopes: none 77 | Protocols: -DefaultRoute -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported 78 | 79 | Link 4 (sdwan0) 80 | Current Scopes: DNS 81 | Protocols: +DefaultRoute -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported 82 | Current DNS Server: 100.95.0.251 83 | DNS Servers: 100.95.0.251 100.95.0.252 100.95.0.253 100.95.0.254 84 | DNS Domain: ~. 85 | ``` 86 | 87 | However, when running a docker container that address is also copied to its `resolv.conf` file but the logic on when to use it is lost. 88 | Depending on the order of nameservers in `resolv.conf` - `168.63.129.16` might appear first and override the system's DNS preventing requests from reaching the Twingate Client. 89 | The only workaround is to remove that nameserver from the container's `resolv.conf` file (it will never need it anyway as its not an Azure resource). 90 | -------------------------------------------------------------------------------- /action.yml: -------------------------------------------------------------------------------- 1 | name: 'Connect to Twingate' 2 | description: 'Connects to Twingate protected resources from your Github Action workflow' 3 | branding: 4 | icon: 'arrow-right-circle' 5 | color: 'black' 6 | inputs: 7 | service-key: 8 | description: 'Twingate Service Key' 9 | required: true 10 | debug: 11 | description: 'Enable debug output' 12 | required: false 13 | default: "false" 14 | runs: 15 | using: "composite" 16 | steps: 17 | - name: Error if unsupported runner.os 18 | if: runner.os != 'Linux' && runner.os != 'Windows' 19 | shell: bash 20 | run: | 21 | echo "Unsupported Runner OS: ${{ runner.os }}" 22 | exit 1 23 | 24 | - name: Install Twingate (Linux) 25 | if: runner.os == 'Linux' 26 | shell: bash 27 | run: | 28 | sudo apt update 29 | echo "deb [trusted=yes] https://packages.twingate.com/apt/ /" | sudo tee /etc/apt/sources.list.d/twingate.list 30 | sudo apt-get update -o Dir::Etc::sourcelist="sources.list.d/twingate.list" -o Dir::Etc::sourceparts="-" -o APT::Get::List-Cleanup="0" 31 | sudo apt install -yq twingate 32 | 33 | - name: Setup and start Twingate (Linux) 34 | if: runner.os == 'Linux' 35 | shell: bash 36 | run: | 37 | echo '${{ inputs.service-key }}' | sudo twingate setup --headless - 38 | MAX_RETRIES=5 39 | WAIT_TIME=5 40 | n=0 41 | 42 | while [ $n -lt $MAX_RETRIES ];
