| # TODO to make (even) more resilient: |
| # - Check if jq is installed |
| # - Make sure bash is v4.3 or later. Can't do until all Azure nodes on the latest version |
| # - Make sure we are not running as local system. Can't do until all Azure nodes are updated. |
| # - Error if docker versions are not equal. Can't do until all Azure nodes are updated |
| # - Error if go versions are not equal. Can't do until all Azure nodes are updated. |
| # - Error if running 32-bit posix tools. Probably can take from bash --version and check contains "x86_64" |
| # - Warn if the CI directory cannot be deleted afterwards. Otherwise turdlets are left behind |
| # - Use %systemdrive% ($SYSTEMDRIVE) rather than hard code to c: for TEMP |
| # - Consider cross builing the Windows binary and copy across. That's a bit of a heavy lift. Only reason |
| # for doing that is that it mirrors the actual release process for docker.exe which is cross-built. |
| # However, should absolutely not be a problem if built natively, so nit-picking. |
| # - Tidy up of images and containers. Either here, or in the teardown script. |
