I think about installing a docker system on my local test server with ubuntu 16.04. I already installed lamp with many test applications.
Can I use docker with mysql, apache and php parallel on the same server without compromising the already installed and used system or do i have to set up a virtual box system before?
You can definitely install Docker with all the lamp stack as containers, and that will not affect the already running apps.
You will only have to remap the docker container ports to custom ports
(ex: apache 80->8080)

So I have a use case where I need to detect inside of a WSL2 VM whether the Docker setup is Docker for Windows w/ WSL integration vs Docker just running inside of the WSL VM (say installed directly via apt or dnf). The networking situation between these two use cases is different because with Docker for Windows WSL integration you cannot reach containers by their IP from the WSL VM. This poses some problems for some dev-tooling that we have and wasn't previously an issue with devs running on Linux-native machines but we've recently run into it now that some devs are using Windows machines with WSL and Docker for Windows.
Any thoughts on how I can do this? Look for specific env vars, mount points etc?
Looks like I can just stat /mnt/wsl/docker-desktop and see if that exists.
I am very new to Docker as a whole.
I have a VPS with Debian 10 Buster, running Docker. I also installed Docker Desktop on my windows 10 pc. I like the GUI, and I googled if i can manage my VPS docker with this application, but found no answear.
Is this possible, or am i missing something obvious?
While I have not been able to connect the Windows 10 Docker Desktop application to my Docker engine running on my Debian 10 VPS, I found an alternative:
portainer.io
This is a service, with a free plan option(CE). You install this docker image following their documentation, and it runs on the host machine, in my case, the Debian VPS. I use this image on port 9000, so all I have to do to access it is open a browser and navigate to http://HOSTIPADDRESS:9000.
There you will find a gui similar to the Docker Desktop application.
I have to do PHP development, for this I was given an Windows 10 machine, this is something I cannot change. So I use the WSL2 feature to setup and development server using Ubuntu 20.04.
First attempt:
Used Windows with Docker Desktop. I configured the environment but was had issues. The mapping between of the project volume and Docker caused important processed like Composer, git etc to be very slow. So this is considered unworkable for me.
Second attempt:
Setup a development environment directly in the WSL2 instance. This works. I'm able to connect with the Xdebug debugger using PhpStorm. But again the rest of the operations are very slow and is considered unworkable for me.
Third attempt:
I was advised to do the following: Create WSL2 Ubuntu 20.04 instance. Install docker on it and store the project folder directly in \\wsl$. In this WSL2 instance I run a docker webserver container. The webserver becomes accessible by localhost.
This seems to work very good, not sure why though... The websites running on the docker webserver are very fast and executing git or composer commands are fast. I open the project folder directly from the \\wsl$ location with PhpStorm.
The only issue I'm having is that I'm unable to create Xdebug session using PhpStorm.
My question is: How to configure the development environment so I can use Xdebug?
Facts & specs
Windows 10 as host machine.
WSL instance: Ubuntu 20.04
Docker webserver instance: Ubuntu 20.04 (php7.4-fmp and apache2, xdebug 3.0.3 port 9000)
The docker webserver container can access the host network (192.x.x.x.)
The docker webserver container can access the WSL network (172.20.x.x)
I use the following xdebug settings:
xdebug.mode = debug
xdebug.client_host = host.docker.internal (this goes to the 192.x.x. address)
Any advise on how to make Xdebug work in this setup?
here's the thing: I tried to install docker inside a windows which runs inside virtualbox, and off course I failed due it's not possible (now I know this is due Hyper-V not used by virtualbox and required by docker).
Since for me migrating to VMWare ain't an option, I dig a little bit and found out that there's no problem on running docker inside a linux distro (which runs inside a vbox), so here's the question.
Is it possible to run 2 different virtual machines with virtualbox, one with linux (running docker inside it), and the other one with windows as my development environment, both at the same time and to develop on windows and then deploy and run tests on docker? If this is possible, how? Any links or keywords for me to search for would be appreciated.
Sure! You need to do following steps:
You should set your VMs network so then can see easily each other https://superuser.com/questions/119732/how-to-do-networking-between-virtual-machines-in-virtualbox
You should expose docker daemon on TCP socket on VM with linux https://success.docker.com/article/how-do-i-enable-the-remote-api-for-dockerd
On VM with windows you need to create some override for docker client so he will connect to remote daemon on linux machine https://gist.github.com/kekru/4e6d49b4290a4eebc7b597c07eaf61f2#create-bat-file-for-windows
Please keep in mind when you expose some service under ports you won't access that on VM with windows on localhost - instead of that you need to type: :
How do I run Datalab locally when it requires Docker (and Docker Toolbox is not supported as documented here: https://cloud.google.com/datalab/docs/quickstarts/quickstart-local)? The Docker website says Docker requires Windows 10 Professional or Enterprise 64-bit, and most corporate environments don't run Windows 10.
Docker is highly preferred over Docker Toolbox, as its a simpler, self-contained installation, with simpler configuration (since you don't have additional virtualization software to deal with, as you do with Docker Toolbox - namely boot2docker and its underlying functionality). However if you have a setup to run docker on your end, you should theoretically be able to use that for running the Datalab docker container by adapting the instructions.
You do have the option of running everything on a GCE VM.
I was facing the same problem, what I found more comfrotable in the end is to install Ubuntu on Virtual Box. This is free and fairly easy, and from the virtual machine you can use all the Docker and the Google guide to run Datalab locally.
