# TODO to make (even) more resilient:
|
|
# - Wait for daemon to be running before executing docker commands
|
|
# - 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.
