## Docker-Sync
|
||||
## Speed up with docker-sync
|
||||
|
||||
Docker on the Mac [is slow](https://github.com/docker/for-mac/issues/77), at the time of writing. Especially for larger projects, this can be a problem. The problem is [older than March 2016](https://forums.docker.com/t/file-access-in-mounted-volumes-extremely-slow-cpu-bound/8076) - as it's a such a long-running issue, we're including it in the docs here.
|
||||
Docker for Mac is [slow](https://github.com/docker/for-mac/issues/77) due to poor performance when the application accesses files shared with the host machine.
|
||||
One solution is to use [docker-sync](https://github.com/EugenMayer/docker-sync).
|
||||
|
||||
The problem originates in bind-mount performance on MacOS. Docker for Mac uses osxfs by default. This is not without reason, it has [a lot of advantages](https://docs.docker.com/docker-for-mac/osxfs/).
|
||||
In simple terms, docker-sync creates a docker container with a copy of all the application files that can be accessed very quickly from the other containers.
|
||||
On the other hand, docker-sync runs a process on the host machine that continuously tracks and updates files changes from the host to this intermediate container.
|
||||
|
||||
Solutions to resolve this issue are easily installed however, we're hoping it'll be fixed by Docker themselves over time. They are currently [adding "cached and delegated" options](https://github.com/docker/for-mac/issues/77#issuecomment-283996750), which is partly available for Docker Edge.
|
||||
Out of the box, it comes pre-configured for OS X, but using it on Windows is very easy to set-up by modifying the `DOCKER_SYNC_STRATEGY` on the `.env`
|
||||
|
||||
Options are [to switch over to NFS](https://github.com/IFSight/d4m-nfs) which is the simplest. The fastest option is [Docker-Sync "native"](https://github.com/EugenMayer/docker-sync) which is still quite easy to install.
|
||||
#### Usage
|
||||
|
||||
Clone [this repo](https://github.com/EugenMayer/docker-sync-boilerplate) to your machine, copy `default/docker-sync.yml` to your Laradock directory and run `docker-sync-stack start`. Be sure to use `docker-sync-stack clean` to stop and `docker-compose build` to rebuild. More information can be found [in the Docker-sync docs](https://github.com/EugenMayer/docker-sync).
|
||||
Laradock comes with `sync.sh`, an optional bash script, that automates installing, running and stopping docker-sync. Note that to run the bash script you may need to change the permissions `chmod 755 sync.sh`
|
||||
|
||||
1) Configure your Laradock environment as you would normally do and test your application to make sure that your sites are running correctly.
|
||||
|
||||
2) Make sure to set `DOCKER_SYNC_STRATEGY` on the `.env`. Read the [syncing strategies](https://github.com/EugenMayer/docker-sync/wiki/8.-Strategies) for details.
|
||||
```
|
||||
# osx: 'native_osx' (default)
|
||||
# windows: 'unison'
|
||||
# linux: docker-sync not required
|
||||
|
||||
DOCKER_SYNC_STRATEGY=native_osx
|
||||
```
|
||||
|
||||
2) Install the docker-sync gem on the host-machine:
|
||||
```bash
|
||||
./sync.sh install
|
||||
```
|
||||
3) Start docker-sync and the Laradock environment.
|
||||
Specify the services you want to run, as you would normally do with `docker-compose up`
|
||||
```bash
|
||||
./sync.sh up nginx mysql
|
||||
```
|
||||
Please note that the first time docker-sync runs, it will copy all the files to the intermediate container and that may take a very long time (15min+).
|
||||
4) To stop the environment and docker-sync do:
|
||||
```bash
|
||||
./sync.sh down
|
||||
```
|
||||
|
||||
#### Setting up Aliases (optional)
|
||||
|
||||
You may create bash profile aliases to avoid having to remember and type these commands for everyday development.
|
||||
Add the following lines to your `~/.bash_profile`:
|
||||
|
||||
```bash
|
||||
alias devup="cd /PATH_TO_LARADOCK/laradock; ./sync.sh up nginx mysql" #add your services
|
||||
alias devbash="cd /PATH_TO_LARADOCK/laradock; ./sync.sh bash"
|
||||
alias devdown="cd /PATH_TO_LARADOCK/laradock; ./sync.sh down"
|
||||
```
|
||||
|
||||
Now from any location on your machine, you can simply run `devup`, `devbash` and `devdown`.
|
||||
|
||||
|
||||
#### Additional Commands
|
||||
|
||||
Opening bash on the workspace container (to run artisan for example):
|
||||
```bash
|
||||
./sync.sh bash
|
||||
```
|
||||
Manually triggering the synchronization of the files:
|
||||
```bash
|
||||
./sync.sh sync
|
||||
```
|
||||
Removing and cleaning up the files and the docker-sync container. Use only if you want to rebuild or remove docker-sync completely. The files on the host will be kept untouched.
|
||||
```bash
|
||||
./sync.sh clean
|
||||
```
|
||||
|
||||
**Additional Notes:**
|
||||
|
||||
- You may run laradock with or without docker-sync at any time using with the same `.env` and `docker-compose.yml`, because the configuration is overridden automatically when docker-sync is used.
|
||||
- You may inspect the `sync.sh` script to learn each of the commands and even add custom ones.
|
||||
- If a container cannot access the files on docker-sync, you may need to set a user on the Dockerfile of that container with an id of 1000 (this is the UID that nginx and php-fpm have configured on laradock). Alternatively, you may change the permissions to 777, but this is **not** recommended.
|
||||

||||
