Run OPA locally with multiple bundle files

[mason-liu]

I am going to run OPA locally with multiple bundles, when I look at the config file, looks like it is for remote bundles only. I can specify -b for local bundle, seems it is only for one, is there any way I can try in my local with multiple bundles?

Yeah, this is possible. You just need to set the roots in the bundle manifests.

$ tree -a .
.
├── bundle1
│   ├── .manifest
│   └── pkg.rego
├── bundle1.tar.gz
├── bundle2
│   ├── .manifest
│   └── pkg.rego
└── bundle2.tar.gz

2 directories, 6 files

tmp.M6tGVplX $ cat bundle1/pkg.rego 
package bundle1

pkg := "bundle1"

tmp.M6tGVplX $ cat bundle1/.manifest 
{"roots": ["bundle1"]}

tmp.M6tGVplX $ cat bundle2/pkg.rego 
package bundle2

pkg := "bundle1"

tmp.M6tGVplX $ cat bundle2/.manifest 
{"roots": ["bundle2"]}

tmp.M6tGVplX $ opa build -b bundle1 -o bundle1.tar.gz
tmp.M6tGVplX $ opa build -b bundle2 -o bundle2.tar.gz
tmp.M6tGVplX $ opa run -s -b bundle1.tar.gz -b bundle2.tar.gz
{"addrs":[":8181"],"diagnostic-addrs":[],"level":"info","msg":"Initializing server. OPA is running on a public (0.0.0.0) network interface. Unless you intend to expose OPA outside of the host, binding to the localhost interface (--addr localhost:8181) is recommended. See https://www.openpolicyagent.org/docs/latest/security/#interface-binding","time":"2023-07-10T10:14:18+01:00"}

then to see the data, via the REST API, in another tab:

tmp.M6tGVplX $ curl "http://localhost:8181/v1/data" | jq
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100    69  100    69    0     0  11876      0 --:--:-- --:--:-- --:--:-- 69000
{
  "result": {
    "bundle1": {
      "pkg": "bundle1"
    },
    "bundle2": {
      "pkg": "bundle1"
    }
  }
}

This shows that both bundles have been loaded.
