redeploy option with deployMar REST API

[Anon Anon]

When using VSManager.exe to deploy a Virtual Service mar file, there is both a --deploy and a --redeploy option. When using the REST API, there seems to only be a deploy equivalent (the 'deployMar' API call) but no equivalent for redeploy. Is that correct, or have I missed something?

Did you try to deploy a new mar and then re-deploy with the same API call and it did not work?

 

Thanks!

If you deploy again, it will overlay previously deployed..

 

the commandline surfaces the difference, which u can do with the rest api as well..

get the existing services, and if the names match it is a redeploy.

 

I use this in my scripts to validate that the service you want to stop is already there and running, etc

Hi,

Let me elaborate - if I execute:

curl -u USERNAME:PASSWORD -F "file=@FILENAME.mar" http://LISAHOST:LISAPORT/api/Dcm/VSEs/VSE1/actions/deployMar

Where that service name does not exist, the operation is successful. If I then execute it again I get the error "There is already a service with the name SERVICENAME".

I should add that this is LISA 7.5.1!

I did a sccript in groovy to use the API REST for the deploy:

 

import org.apache.http.entity.mime.MultipartEntityBuilder

import org.apache.http.entity.mime.content.ByteArrayBody

import groovyx.net.http.HttpResponseDecorator

 

def httpBuilder = new HTTPBuilder("http://XXXXXXXX:1505/api/Dcm/VSEs/${vse}/actions/deployMar")

String filename = "${vsiFileDir}/${testname}.mar"

def login = "${username}:${password}".bytes.encodeBase64().toString()

httpBuilder.request (Method.POST) { multipartRequest ->

       headers.'Authorization' ="Basic ${login}"

       MultipartEntityBuilder multipartRequestEntity = new MultipartEntityBuilder()

       multipartRequestEntity.addPart('file', new ByteArrayBody(

       IOUtils.toByteArray(new FileInputStream(new File(filename)))))

       multipartRequest.entity = multipartRequestEntity.build()

 

       response.success = { HttpResponseDecorator resp3, data3 ->

            if (resp3.getStatus() == 201) { //201 created OK

                 log.info("Deploy Mar OK")

            } else {

                 log.info("Failure of deploy Mar")

            }

       }

       response.failure = { HttpResponseDecorator resp3, data3 ->

            log.error("Failure of deploy Mar")

       }

  }

 

Please let me know if you have any questions.

Hi Relbou,

 

Well, my main question would be what your findings were using this code. Were you able to call this code twice in a row with a successful response code? Did you get a successful response the first time and an error the second time, which would be conistent with what I am experiencing? What version of LISA where you using?

 

I very much appreciate the effort you put in providing actual code in your reply, but my query was around the API behaviour rather than how to call the API. Your finidngs when you executed the code are much more valuable than the code itself!

[Relbou]

For reply to your question: you don't have a redeploy function in REST API but you can do a delete and a deploy.

[Anon Anon]

Ah, thank you, that's what I was trying to verify. It's a shame, becasue the redeploy of VSManager means much less downtime (not zero, but minimal). Whereas the delete and deploy via the REST API will certainly mean more downtime and will push me down the VSManager route, even though I'd prefer to use the REST API with its superior output...
