Add the admin account as `deuxfleurs` to your `~/.mc/config` file
|
|
|
|
You need to choose some names/identifiers:
|
|
|
|
```bash
|
|
export ENDPOINT="https://s3.garage.tld"
|
|
export SERVICE_NAME="example"
|
|
|
|
|
|
export BUCKET_NAME="backups-${SERVICE_NAME}"
|
|
export NEW_ACCESS_KEY_ID="key-${SERVICE_NAME}"
|
|
export NEW_SECRET_ACCESS_KEY=$(openssl rand -base64 32)
|
|
export POLICY_NAME="policy-$BUCKET_NAME"
|
|
```
|
|
|
|
Create a new bucket:
|
|
|
|
```bash
|
|
mc mb deuxfleurs/$BUCKET_NAME
|
|
```
|
|
|
|
Create a new user:
|
|
|
|
```bash
|
|
mc admin user add deuxfleurs $NEW_ACCESS_KEY_ID $NEW_SECRET_ACCESS_KEY
|
|
```
|
|
|
|
Add this new user to your `~/.mc/config.json`, run this command before to generate the snippet to copy/paste:
|
|
|
|
```
|
|
cat > /dev/stdout <<EOF
|
|
"$NEW_ACCESS_KEY_ID": {
|
|
"url": "$ENDPOINT",
|
|
"accessKey": "$NEW_ACCESS_KEY_ID",
|
|
"secretKey": "$NEW_SECRET_ACCESS_KEY",
|
|
"api": "S3v4",
|
|
"path": "auto"
|
|
},
|
|
EOF
|
|
```
|
|
|
|
---
|
|
|
|
Create a policy for this bucket and save it as json:
|
|
|
|
```bash
|
|
cat > /tmp/policy.json <<EOF
|
|
{
|
|
"Version": "2012-10-17",
|
|
"Statement": [
|
|
{
|
|
"Effect": "Allow",
|
|
"Action": [
|
|
"s3:ListBucket"
|
|
],
|
|
"Resource": [
|
|
"arn:aws:s3:::${BUCKET_NAME}"
|
|
]
|
|
},
|
|
{
|
|
"Effect": "Allow",
|
|
"Action": [
|
|
"s3:*"
|
|
],
|
|
"Resource": [
|
|
"arn:aws:s3:::${BUCKET_NAME}/*"
|
|
]
|
|
}
|
|
]
|
|
}
|
|
EOF
|
|
```
|
|
|
|
Register it:
|
|
|
|
```bash
|
|
mc admin policy add deuxfleurs $POLICY_NAME /tmp/policy.json
|
|
```
|
|
|
|
Set it to your user:
|
|
|
|
```bash
|
|
mc admin policy set deuxfleurs $POLICY_NAME user=${NEW_ACCESS_KEY_ID}
|
|
```
|
|
|
|
Now it should display *only* your new bucket when running:
|
|
|
|
```bash
|
|
mc ls $NEW_ACCESS_KEY_ID
|
|
```
|
|
|

|

|
|
Now we need to initialize the repository with restic.
|
|
|
|
```bash
|
|
export AWS_ACCESS_KEY_ID=$NEW_ACCESS_KEY_ID
|
|
export AWS_SECRET_ACCESS_KEY=$NEW_SECRET_ACCESS_KEY
|
|
export RESTIC_REPOSITORY="s3:$ENDPOINT/$BUCKET_NAME"
|
|
export RESTIC_PASSWORD=$(openssl rand -base64 32)
|
|
```
|
|
|
|
Then init the repo for restic from your machine:
|
|
|
|
```
|
|
restic init
|
|
```
|
|
|
|
*I am using restic version `restic 0.12.1 compiled with go1.16.9 on linux/amd64`*
|
|
|
|
See your snapshots with:
|
|
|
|
```
|
|
restic snapshots
|
|
```
|
|
|
|
Check also these useful commands:
|
|
|
|
```
|
|
restic ls
|
|
restic diff
|
|
restic help
|
|
```
|

Add the secrets to Consul, near your service secrets.
|
|
The idea is that the backuping service is a component of the global running service.
|
|
You must run in `app/<name>/secrets/<subpath>`:
|
|
|
|
```bash
|
|
echo "USER Backup AWS access key ID" > backup_aws_access_key_id
|
|
echo "USER Backup AWS secret access key" > backup_aws_secret_access_key
|
|
echo "USER Restic repository, eg. s3:https://s3.garage.tld" > backup_restic_repository
|
|
echo "USER Restic password to encrypt backups" > backup_restic_password
|
|
```
|
|
|
|
Then run secretmgr:
|
|
|
|
```bash
|
|
# Spawning a nix shell is an easy way to get all the dependencies you need
|
|
nix-shell
|
|
|
|
# Check that secretmgr works for you
|
|
python3 secretmgr.py check <name>
|
|
|
|
# Now interactively feed the secrets
|
|
python3 secretmgr.py gen <name>
|
|
```
|
|
|
|
---
|
|
|
|
Now we need a service that runs:
|
|
|
|
```
|
|
restic backup .
|
|
```
|
|
|
|
And also that garbage collect snapshots.
|
|
I propose:
|
|
|
|
```
|
|
restic forget --prune --keep-within 1m1d --keep-within-weekly 3m --keep-within-monthly 1y
|
|
```
