goaci

ACI client library for Go

GoACI is a Go client library for Cisco ACI. It features a simple, extensible API, advanced JSON manipulation, and a backup client for running queries against the backup file.

Getting Started

Installing

To start using GoACI, install Go and go get:

$ go get -u github.com/brightpuddle/goaci

Basic Usage

package main

import "github.com/brightpuddle/goaci"

func main() {
    apic, _ := goaci.NewAPIC("1.1.1.1", "user", "pwd")
    if err := apic.Login(); err != nil {
        panic(err)
    }

    res, _ = apic.Get("/api/mo/uni/tn-infra")
    println(res.Get("imdata.0.*.attributes.name"))
}

This will print:

infra

Result manipulation

goaci.Result uses GJSON to simplify handling JSON results. See the GJSON documentation for more detail.

res, _ := GetClass("fvBD")
res.Get("0.fvBD.attributes.name").Str // name of first BD
res.Get("0.*.attributes.name").Str // name of first BD (if you don't know the class)

for _, bd := range res.Array() {
    println(res.Get("*.attributes|@pretty")) // pretty print BD attributes
}

for _, bd := range res.Get("#.fvBD.attributes").Array() {
    println(res.Get("@pretty") // pretty print BD attributes
}

Helpers for common patterns

res, _ := GetDn("uni/tn-infra")
res, _ := GetClass("fvTenant")

Query parameters

Pass the goaci.Query object to the Get request to add query paramters:

queryInfra := goaci.Query("query-target-filter", `eq(fvTenant.name,"infra")`)
res, _ := apic.GetClass("fvTenant", queryInfra)

Pass as many paramters as needed:

res, _ := apic.GetClass("isisRoute",
    goaci.Query("rsp-subtree-include", "relations"),
    goaci.Query("query-target-filter", `eq(isisRoute.pfx,"10.66.0.1/32")`,
)

POST data creation

goaci.Body is a wrapper for SJSON. SJSON supports a path syntax simplifying JSON creation.

exampleTenant := goaci.Body{}.Set("fvTenant.attributes.name", "goaci-example").Str
apic.Post("/api/mo/uni/tn-goaci-example", exampleTenant)

These can be chained:

tenantA := goaci.Body{}.
    Set("fvTenant.attributes.name", "goaci-example-a").
    Set("fvTenant.attributes.descr", "Example tenant A")

...or nested:

attrs := goaci.Body{}.
    Set("name", "goaci-example-b").
    Set("descr", "Example tenant B").
    Str
tenantB := goaaci.Body{}.SetRaw("fvTenant.attributes", attrs).Str

Token refresh

Token refresh is handled automatically. The APIC client keeps a timer and checks elapsed time on each request, refreshing the token every 8 minutes. This can be handled manually if desired:

apic, _ := goaci.NewAPIC("1.1.1.1", "user", "pwd")
apic.Login()

res, _ := apic.Get("/api/...", goaci.NoRefresh)
apic.Refresh()

Backup client

goACI also features a "backup" client for querying ACI .tar.gz backup files. This client partially mirrors the API of the HTTP client.

backup, _ := goaci.NewBackup("config.tar.gz")

res, _ := backup.GetDn("uni/tn-infra")
res, _ = backup.GetClass("fvBD")
