drawbridge

A command line application that helps deploy and verify projects that build deterministically. While this tool is used and tested regularly by its maintainers, it's still under active development. Use at your own risk.

The following programs need to be installed and available on your PATH:

• node
• npm
• docker
• git

Installation

Example .drawbridgerc File

{
  "environments": {
    "develop": {
      "gitUrl": "git@github.com:skubakdj/MyCrypto.git",
      "distFolder": "dist/prod",
      "buildCommand": "yarn && npm run build"
    },
    "staging": {
      "gitUrl": "git@github.com:skubakdj/MyCrypto-Staging.git",
      "distFolder": "docs"            
    },
    "prod": {
      "gitUrl": "git@github.com:skubakdj/MyCrypto-Production.git",
      "distFolder": "docs"
    }
  }
}

Command Examples

Push develop to staging from develop commit bfeeab:

drawbridge push develop to staging --fromCommit bfeeab --commitMessage "test-release-a" --newBranch "test-branch-a"

---

Verify develop to staging from develop commit bfeeab to staging branch test-branch-a:

drawbridge verify develop to staging --fromCommit bfeeab --toBranch "test-branch-a"

---

Real World Example of Verification

Sometimes actual examples help, especially while troubleshooting:

• Repo: download.mycrypto.com
• Latest commit: 995152190a517ea561dce833ce940c6f70e60e80
• Branch / Pull Request: #38
• Commit on the Pull Request: b7fe92393c146396652bf146b93fd14f621e8d2e
• .drawbridgerc file:

{
    "environments": {
        "develop": {
            "gitUrl": "git@github.com:MyCryptoHQ/download.mycrypto.com.git",
            "distFolder": "dist",
            "buildCommand": "yarn && yarn build"
        },
        "prod": {
            "gitUrl": "git@github.com:MyCryptoHQ/download.mycrypto.com.git",
            "distFolder": "",
            "defaultBranch": "gh-pages"
        }
    }
}

To push:

drawbridge push develop to prod --fromCommit 995152190a517ea561dce833ce940c6f70e60e80 --commitMessage "release-08-03-a" --newBranch "release-08-03-a"

Upon completion, a new branch will appear on the repo.

Then a pull request will be opened from that branch to the master branch.

Then, to verify:

drawbridge verify develop to prod --fromCommit 995152190a517ea561dce833ce940c6f70e60e80 --toBranch "release-08-03-a"

The output in terminal should be:

✔ Bootstrapped
✔ Cloned develop to /tmp/drawbridge/wtf2tiknaz/develop
✔ Checked out commit 995152190a517ea561dce833ce940c6f70e60e80 from environment develop
✔ Built Docker image
✔ Built develop with Docker
✔ Analyzed directory /tmp/drawbridge/wtf2tiknaz/develop/dist
✔ Cloned prod to /tmp/drawbridge/wtf2tiknaz/prod
✔ Checked out branch release-08-03-a from environment prod
✔ Analyzed directory /tmp/drawbridge/wtf2tiknaz/prod
✔ develop hash:	f119bb7433113b9574943961e8ee32b7c877b20c032ea03f746768496b1fcd2a
✔ prod hash:	f119bb7433113b9574943961e8ee32b7c877b20c032ea03f746768496b1fcd2a
✔ Hashes are a match!

Troubleshooting tips:

• Are you in the correct repo in terminal? You should be in the folder you are building / verifying (your project folder) NOT the drawbridge folder.
• Are you using the correct commit hashes in the correct places?
• Try doing a git fetch in the project folder
• Double check all commit hashes again. The first commit hash should be from the main repo (the branch you are merging into) NOT the commit hash of the pull request
• Try uninstalling / reinstalling drawbridge and trying again
• Ping the team on Slack, open a github issue, or email support at mycrypto dot com
