This updates to support updating things like `linuxkit/runc:v0.3` to a new hash
(or tag).
Running:
./scripts/update-component-sha.sh --image linuxkit/runc 100d0d046c
Still DTRT and updates runc to that (bogus) sha.
Furthermore, running:
./scripts/update-component-sha.sh --image linuxkit/runc v0.4
Updates runc to that (bogus) release (this worked before) but now running:
./scripts/update-component-sha.sh --image linuxkit/runc acba8886e4
Inverts things and puts them back.
(this is not quote a nop because
src/cmd/linuxkit/vendor/github.com/moby/tool/src/moby/linuxkit.go has a
different sha in it which is not put back)

$0 --<mode> <how-to-find> <new-hash>
|
|
|
|
Available modes: --hash and --image
|
|
|
|
Replace by hash:
|
|
$0 --hash <OLD> <NEW>
|
|
Example: $0 --hash 8675309abcdefg abcdef567899
|
|
Will replace all instances of 8675309abcdefg with abcdef567899
|
|
|
|
Replace by image: $0 --image <IMAGE> <NEW>
|
|
$0 --image <IMAGE> <NEW>
|
|
Example: $0 --image linuxkit/foo abcdef567899
|
|
Will tag all instances of linuxkit/foo with abcdef567899
|
|
|
|
$0 --image <IMAGE>:<NEW> is accepted as a convenient shortcut for cutting
|
|
and pasting e.g.the output of linuxkit pkg show-tag
|
|
|
|
By default, for convenience, if no mode is given (--image or --hash), the first method (--hash) is assumed.
|
|
Thus the following are equivalent:
|
|
$0 <OLD> <NEW>
|
|
$0 --hash <OLD> <NEW>
