问题 I have created a dockerfile and docker-compose like below, which is suppost to create an image of tomcat inside my container and edit the tomcat users so that I am able to access the manager gui. The four files below are all in the same folder as where I run the docker-compose up command. docker-compose.yml version: '2' services: tomcat: build: . container_name: development ports: - 8001:8080 environment: - spring.profiles.active=development Dockerfile FROM tomcat COPY tomcat-users.xml /usr

std::string a container

点点圈 提交于 2019-12-06 02:09:36
Is std::string a container class in standard c++ library, restricted to hold only char elements? It's a typedef of std::basic_string<char> , actually. std::basic_string is a container class specifically designed for string operations. This container can be used for wide characters ( wchar_t ) as well; for that case its typedef would be wstring . A std::basic_string<> is a class that is very much like a sequence container. Note that std::basic_string can contain any POD type, not just elements of type char (which is what a std::string is) or wchar_t ( std::wstring ). I believe that a basic

What would be the “distinct method” that Traversable has in addition to Foldable?

≡放荡痞女 提交于 2019-12-05 23:21:26
问题 Foldable is a superclass of Traversable, similarly to how Functor is a superclass of Applicative and Monad . Similar to the case of Monad , where it is possible to basically implement fmap as liftM :: Monad m => (a->b) -> m a -> m b liftM f q = return . f =<< q we could also emulate foldMap as foldLiftT :: (Traversable t, Monoid m) => (a -> m) -> t a -> m foldLiftT f = fst . traverse (f >>> \x -> (x,x)) -- or: . sequenceA . fmap (f >>> \x -> (x, x)) using the Monoid m => (,) m monad. So the

Connect Rails/Unicorn/Nginx container to MySQL container

Related to this thread, I am trying to create 2 containers: 1 with a rails app, and the other with a MySQL database but I keep getting the Mysql2::Error (Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' in my apps production.log file after I hit the container's IP http://192.168.59.103 When I start the rails container, I am attempting to link them and do get an error if I specify an incorrect MySQL name. What am I missing to successfully link the containers so the full app runs in containers? Rails container command docker run --name games-app --link test-mysql

How to iterating a Quad/Oct tree

萝らか妹 提交于 2019-12-05 21:28:51
I am having a difficult time grasping how to iterate an octree or quad. And it may be because I am not experienced with different mythologies of iterating. But let’s suppose that I produced a quad tree that holds float x,y,z; dword color. Now, Let’s also say that this node can only produce 4 children at a time (and those children can both produced 4 children, etc, etc) up until: 7 levels are reached (so that child can’t create anymore children, but its brothers/sisters can), all 4 children created are the same dword color (again, if that happens, its brothers/sisters can still produce), or

Is there a standard way to convert from container<Type1> to container<Type2>?

问题 I have two classes A and B , and an implicit conversion operator exists to go from one to the other, so that: A a; B b; b = a; // Works Is there a standard way to convert a std::list<A> to a std::list<B> ? (Or even from std::vector<A> to a std::list<B> ). I know I can iterate trough to the list and build the second list item by item, but I wonder if there is a more elegant solution. Unfortunately I cannot use boost but out of curiosity as a bonus question, if boost can handle this, I'd be

Can we inherit from Qt containers?

纵然是瞬间 提交于 2019-12-05 19:02:16
Are we supposed to be able to inherit from Qt containers such as QList , QVector or QMap in order to specialize them and add functionality? If so, what do we need to do in order to be sure that the container works correctly (virtual methods, virtual destructor etc..?). If not, why not and what other options do I have? Both, STL and Qt Containers opt for non virtual destructors. There is an interesting discussion why this is, and why its not fixed with Qt5. QList has no virtual destructor, but is inherited from http://qt-project.org/forums/viewthread/16416 Also, note further differences between

How to scale in/out EC2 instances based on ECS cluster resources availability?

蹲街弑〆低调 提交于 2019-12-05 17:31:22
I have multiple services running in my ECS cluster. Each service contains one or more tasks based on CPU utilization or a number of users. I have deployed these containers with EC2 launch type. Now, I want to increase/decrease the number of EC2 instances based on available resources in the cluster. Let's say there are four ECS tasks running in two m5.large instances. Now, if an ECS service increases the number of tasks and there aren't enough resources available in the cluster, how can I spin up an instance and add to the cluster? And same goes for vice versa. If there is instance running with
