I don't have time to shoot an introduction video, so I'll just grab some pictures and introduce the container environment deviny/phpenv I use. https://github.com/DevinY/phpenvphpenv can be regarded as an evolutionary version of my previous D-Laravel open source project, conceptually extending the use of many Dlaravel operation methods. The update of the container tends to be controlled by the user to build his own image, so I am not very good at changing the version number. In fact, the php version number of D-Laravel seems to have not been changed for a long time:p
Although I like Laravel very much, Laravel has many great features, such as Eloquent ORM, Model, and Blade temple, which I like very much. But seriously, he's really fat, and it's kind of slow to start, so I'm just trying to do it the way I want Extract the functions I want, and assemble this self-made frame micro-frame, which is close to Plain PHP. I think anyone who understands PHP can get started.
Maybe in the old version of the docker environment, when using Docker compose to start the container, you will encounter the following error: Error response from daemon: could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network This is actually this It is a symptom of running out of default-address-pools. In some environments, docker-compose will use the private network of Class B by default. The private IP of segment 172 has a range, from 172.16.0.0 to 172.31.255.255. That is to say, when we start a docker-compose Project, it will eat a private section of Class B, which is very heroic.
