# Rollback workflow
|
||
|
|
|
||
|
|
Build it in this directory.
|
||
|
|
Make sure you have etcd dependency ready. Last time we use etcd v3.0.7.
|
||
|
|
```
|
||
|
|
$ go build .
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
Run it:
|
||
|
|
```
|
||
|
|
$ ./rollback2 --data-dir $ETCD_DATA_DIR --ttl 1h
|
||
|
|
```
|
||
|
|
|
||
|
|
This will rollback KV pairs from v3 into v2.
|
||
|
|
If a key was attached to a lease before, it will be created with given TTL (default to 1h).
|
||
|
|
|
||
|
|
On success, it will print at the end:
|
||
|
|
```
|
||
|
|
Finished successfully
|
||
|
|
```
|
||
|
|
|
||
|
|
Repeat this on all etcd members.
|
||
|
|
|
||
|
|
You can do simple check on keys (if any exists):
|
||
|
|
```
|
||
|
|
etcdctl ls /
|
||
|
|
```
|
||
|
|
|
||
|
|
Important Note
|
||
|
|
------
|
||
|
|
|
||
|
|
This tool isn't recommended to use if any problem comes up in etcd3 backend.
|
||
|
|
Please report bugs and we will fix it soon.
|
||
|
|
|
||
|
|
If it's still preferred to run this tool, please backup all your data beforehand.
|
||
|
|
This tool will also back up datadir to same path with ".rollback.backup" suffix.
|
||
|
|
|
||
|
|
Caveats:
|
||
|
|
- The tool doesn't preserve versions of keys.
|
||
|
|
- If any v2 data exists before rollback, they will be wiped out.
|
||
|
|
- v3 data only exists in the backup after successful rollback.
