| # startup juiceopt backup | ||
| ## prerequire | ||
| 1. prepare S3 strorage （if you want other types of storage, reference the juicfs document），Obtain the access-key and secret-key . In the example of this article, it use minio ,and the instance is minio-1668754867, and the bucket named `test` so the url is http://test.minio-1668754867.minio:9000/ , you can modify it according your situations, and how to do you can refer to juicefs documents. | ||
|
|
||
| 2. Install the redis , although juicefs also support sqlite as meta data storage, buf if you do so, you should sync the meta file from s3 at first,and I do not recommend it. redis url is the form as follow： | ||
| ``` | ||
| redis://<redis-server-name/IP>:<port>/<NO of database> | ||
| ``` | ||
| in the example of this article, redis-server-name is redis-leader, the number of database is 1, So the redis url is `redis://redis-leader:6379/1` | ||
|
|
||
| 3. Verfiy whether it works: suppose the backup directory is juicefs , you can login in Pod's backup container , execute commanas as follow： | ||
|
|
||
| ``` | ||
| juicefs format --storage s3 \ | ||
| --bucket http://test.minio-1668754867.minio:9000/ \ | ||
| --access-key <your access key> \ | ||
| --secret-key <your secrete key> > \ | ||
| redis://redis-leader:6379/1 \ | ||
| juicefs | ||
| ``` | ||
| then execute ： | ||
| `juicefs mount -d redis://redis-leader:6379/1 /juicefs` | ||
|
|
||
| check whether juicefs is exist, write files, and check S3 storage whether has changed. | ||
|
|
||
| ## fill backup crd's yaml configs | ||
| In backup crd's yaml file, such as in samples/mysql_v1alpha_backup.yaml, add fields information under spec: | ||
|
|
||
| ``` | ||
| juiceOpt: | ||
| juiceMeta: <fill your redis url> | ||
| backupSecretName: <S3's secret name, for example:sample-backup-secret> | ||
| juiceName: <juicefs backup directory> | ||
| ``` | ||
| for example: | ||
| ``` | ||
| juiceOpt: | ||
| juiceMeta: "redis://redis-leader:6379/1" | ||
| backupSecretName: sample-backup-secret | ||
| juiceName: juicefs | ||
| ``` | ||
| Others refer to [backup and restore config](./backup_and_restoration_s3.md) | ||
|
|
||
| ## Running backup. | ||
|
|
||
| use command `kubectl apply -f <your backup crd's yaml>` , for examples： | ||
|
|
||
| ``` | ||
| kubectl apply -f config/samples/mysql_v1alpha1_backup.yaml | ||
| ``` | ||
|
|
||
| # Restore | ||
| ## prerequest for restore | ||
| I suppose that the cluster you want restore is `sample2` | ||
| ### and `config map` | ||
| 1. At first give the `config map` a name,name's form is <name of restore cluster>-restore, this article suppose that cluster name is sample2, so `config map`'s name is `sample2-restore` | ||
| 2. Create config map | ||
| * prepare for juiceopt parameters: | ||
| build a yaml file, named `juiceopt.yaml`, fill it with: | ||
| ``` | ||
| juiceMeta: <redis url> | ||
| backupSecretName: <S3's secret name> | ||
| juiceName: <backup directory under S3 bucket> | ||
| ``` | ||
| for example, in the example of this article, juiceopt.yaml is: | ||
| ``` | ||
| juiceMeta: "redis://redis-leader:6379/1" | ||
| backupSecretName: sample-backup-secret | ||
| juiceName: juicefs | ||
| ``` | ||
| * use `kubectl create configmap` create a configmap | ||
| configmap has two keys , `from` and `juice.opt` that respectively indicate the cluster has been backuped which we should restore from, and the juice parameter. | ||
| but `date` key is optional, it indicates the time where restore to (format is:"2006-01-02 09:07:41"), if it does not have got this key , it will restore to now, use the commands as follows: | ||
| `kubectl create configmap sample2-restore --from-literal=from=sample --from-file="juice.opt"=./juiceopt.yaml ` | ||
|
|
||
|
|
||
| ### config mysql cluster's yaml | ||
| in the example of this article, we suppose the cluster need to restore is sample2, the config method can refer to [radondb cluster configuration](./deploy_radondb-mysql_operator_on_k8s.md) | ||
| ### use kubectl apply the yaml | ||
| use `kubectl apply ` apply the yaml file, for the example, use the commands as follow: | ||
|
|
||
| `kubectl apply -f config/samples/mysql_v1alpha1_mysqlcluster.yaml ` | ||
|
|
