docker flask

Preface We have mentioned earlier that if we build the Docker cluster, there will be the need for a Docker instance network connection across the host, and in order to save the IP resources of the host network, we try to use DOCKER0 own network connection, add Host network IP to the main node (container instance), This should be a more desirable business requirement. ---------------------------------------

Application background:Docker is the first to run on Ubuntu and Debian, using AUFS memory. Because Docker is becoming more popular, many companies want to use it on Rhel, but the upstream kernel does not include AUFS, so Rhel cannot use Aufs.Eventually, developers developed a new back-end storage engine Devicemapper, based on existing device mapper technology, and made Docker support pluggable, and now ther

Getting Started with full-text search engine Unfortunately, the support of relational databases for Full-text search is not standardized. Different databases implement Full-text search in their own way, and SQLAlchemy does not provide a good abstraction in Full-text search. We now use SQLite as our database, so we can bypass SQLAlchemy and use the tools provided by SQLite to create a full-text indexing index. But it's not so good because if we switch to another database one day, we have to rew

While Flask is a lightweight framework, it also provides many convenient features such as unit testing and database migration for large Web applications, so let's look at the structure of building large Web applications using the Python flask Framework Example: While small Web applications can be handy with a single script, this approach does not scale well. As applications become more complex, processing

This article describes how to implement full-text search in the Python Flask framework. this basic web function is very simple to implement. For more information, see Getting started with the full-text search engine Unfortunately, the full-text search support of relational databases is not standardized. Different databases use their own methods for full-text retrieval, and SQLAlchemy does not provide a good abstraction for full-text retrieval. We now

Introduction to the Flask signal mechanism (signals) in the Python Web framework, flasksignals Signal (signals) The Flask signal (signals, or event hooking) allows a specific sender to notify the subscriber of what happened (since we know what happened, we can know what to do next ). Flask provides some signals (core signals) and other extensions provide more si

Whether you are entertaining or working on linux, this is a great opportunity for you to program using python. Back to college I want them to teach me Python instead of Java, which is interesting to learn and useful in practical applications such as yum package manager. In this tutorial, I will show you how to use python and a micro-framework called flask to build a simple application to display useful information such as memory usage and CPU percenta
