That file already handles volume mounting operation that and exposes the port to the localhost. To provide a more structured repo, we also integrated a docker-compose manifest file. Currently it only supports 1.4, 1.5, 1.6, 1.7 at the momentĭocker run -v /path/to/hello:/go/src/hello -e GO_VERSION=1.6 -p 7000:7000 canthefason/go-watcher watcher -run hello If you want to change the Go version, you can use GO_VERSION environment variable. If you don't set anything, by default Watcher will pick version 1.7. Currently it only supports major versions right now. In the containerized Watcher, our GOPATH is set to /go directory by default, so you need to mount your project to this GOPATH.ĭocker run -v /path/to/hello:/go/src/hello -p 7000:7000 canthefason/go-watcher watcher -run helloĬontainerized Watcher also supports different versions of Go by leveraging gvm. The most essential thing to run your code in Docker is, mounting your project volume to a container. In our example, we are creating a server that listens to port 7000 and responds to all clients with "watcher is running" string. Let's try to dockerize this example code first. There is an example project under /docker-example directoy. If you want to run Watcher in a containerized local environment, you can achieve this by using canthefason/go-watcher image in Docker Hub.
If your intention is making some changes in place, you can set -watch-vendor flag as "true", and start watching vendor directory. Only configuration we have here is, by default we have excluded vendor/ folder from watched directories. Since Globs and some optional folder arrays will make it harder to configure, we are not planning to have support for a configurable watched folder structure. Watcher -c config -run /username/somerootpackagename -watch /username Vendor directory Watcher -c config -run /username/somerootpackagenameįor the cases where your main function is in another directory other than the dependant package, you can do this by passing a different package name to -watch parameter. If you prefer to use it like go run, you can call watcher with -run flag anywhere you want (we assume that your GOPATH is properly set). Package dependencyīy default Watcher recursively watches all files/folders under working directory. tmpl files and ignores hidden folders and _test.go files. When you run the command, Watcher starts watching folders recursively, starting from the current working directory. Myapp -c config -p 7000 -h localhost With watcherĪs you can see nothing changed between these two calls. You can pass all your existing package arguments to the Watcher, which really lowers the learning curve of the package, and makes it practical. Watcher works like your native package binary. start command supports the following custom parameters: -name'name' -> Run by name on existing configuration -path'realize/server' -> Custom Path (if not specified takes the working directory name) -generate -> Enable. Go install /canthefason/go-watcher/cmd/watcherĪfter this step, please make sure that your go/bin folder is appended to PATH environment variable. realize.yaml file if doesn’t already exist, add the working directory as project and run your workflow. With Watcher, we aimed simplicity in configuration, and tried to make it as simple as possible. Most of the existing file watchers have a configuration burden, and even though Go has a really short build time, this configuration burden makes your binaries really hard to run right away. go file changes, and restarting the app in case of an update/delete/add operation. │ OK │ pkg/foo/bar_test.go │ 258.Watcher is a command line tool inspired by fresh and used for watching.
