In Android programming, what exactly is a Context class and what is it used for? I read about it on the developer site, but I am unable to understand it clearly.
context defines either a path to a directory containing a Dockerfile, or a URL to a git repository. In your case, . is a relative path representing the current directory where you run docker-compose command and where Compose can find a Dockerfile (and obviously also the docker-compose.yaml file).
A context is a variable name -> variable value mapping that is passed to a template. Context processors let you specify a number of variables that get set in each context automatically – without you having to specify the variables in each render () call.
1) Is the useContext hook strictly a means of consuming the context values? 2) Is there a recommended way, using React hooks, to update values from the child component, which will then trigger component re-rendering for any components using the useContext hook with this context?
Context may be an Application, a Service, an Activity, and more. Normally the context of Views in an Activity is the Activity itself so you may think you can just cast this Context to Activity but actually you can't always do it, because the context can also be a ContextThemeWrapper in this case.
Creating context managers is done by implementing __enter__() and __exit__() in a normal class. __enter__() tells what to do when a context manager starts and __exit__() when a context manager exists (giving the exception to the __exit__() method if an exception occurred) A shortcut for creating context managers can be found in contextlib.
try to use BuildKit with DOCKER_BUILDKIT=1 (as mentioned here); try to split your project into smaller parts to optimize content of build context; if you have a complex project you may want to manually collect all necessary files in separate folder before build and use it as a build context for a specific image.
HTTP context accessor Finally, you can use the IHttpContextAccessor helper service to get the HTTP context in any class that is managed by the ASP.NET Core dependency injection system.
3 I am trying to provision a simple keyvault in azure using terraform and I get the following error: Error: retrieving contact for KeyVault: keyvault.BaseClient#GetCertificateContacts: Failure sending request: StatusCode=0 -- Original Error: context deadline exceeded And here's my terraform snippet:
Documentation on the nature of context is pretty sparse at the moment. (There is a long discussion in the Github repo about "making the concept less nebulous".) In a few places in the documentation it's referred to as a "context dictionary" or even an "execution context dictionary", but never really spelled out what that is. Apparently, the Templates Reference is considered to be documentation ...
