Docker: In Dockerfile, copy files temporarily, but not for final image -

-

I have a Java service that I would like to package, and the only thing that is the jar file of the last dock image is Config file However, first of all, I need to run my gradle command to create JAR, but I should not do that the gradle result uses the Docker image.

Here is my current Dockerfile: 

  Get the update exactly & amp; Apt-get install -y openjdk-7-jdk Copy / run ./gradlew shadowJar CMD ["java", "-zer", "service / build / lbs / service.jar", "server", "service / service .imil "]   
 You can see that I have to do the  copy  first so that I can . / Gradlew  (otherwise it says that the command can not be found). But in the end, I only need all the  service.jar  and  service.yml  files.  
 I'm probably missing something, but how do I . / Gradlew  can provide everything during the build phase, but only the result image includes  service.jar  and  service.yml .   
 
 
 An image creation is as follows:  
 
 ... Docker The build command will use the docfiler as the directory that is in the form of a build contact (including all its subdirectories). The build context will be sent to the Doker Damon before creating the image, which means that if you use the source repository, the entire contents of your hard drive will be sent to the daemon ...   < P> See  
 There is no way to achieve what I want you to do. There are two options:  
     
  1.  
     To maintain all the build dependency inside the image and blot your image to create your JR file inside the container.   
  2.  
     I advise to make my jar separately and when they are created, simply executable and config file  ADD  means that all Build dependencies should be available on your development environment, but your image is as small as it can be.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
