gpg: could not parse keyserver URL

[peterceyu]

Trying to install Docker, but below command doesn't work:

$ sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80—recv-keys 58118E89F3A912897C070ADBF76221572C52609D

@peterceyu I can see that you're using both windows and Linux, is this right? These are current installation instructions for Docker - but I'm not sure that you should bother with them if your computer is running windows. https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/#set-up-the-repository

Thanks, Dimitrios. Am trying out both Windows and Ubuntu as I am having problem with both. Former due to Asian character issues, and the later for reasons I don't understand. I tried the installing following https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/#set-up-the-repository, but when I hit "vagrant up --no-parallel' in the terminal, following message comes. Sorry for the trouble, but I really wish to learn what you have written.

Hello Peter, could you send me a TeamViewer invite in **** to set it up for you. It should be quick

Hello Peter,

Made it work in Ubuntu with Docker. There was one necessary change in the Vagrantfile:

--- a/Vagrantfile
+++ b/Vagrantfile
@@ -1,7 +1,7 @@
 ENV['VAGRANT_DEFAULT_PROVIDER'] = "docker"

 host_vagrantfile = "./Vagrantfile.dockerhost"
-force_host_vm = TRUE
+force_host_vm = FALSE

Then I did sudo vagrant up --no-parallel:

$ sudo vagrant up --no-parallel

It all started successfully.

$ sudo vagrant status
Current machine states:

web                       running (docker)
spark                     running (docker)
es                        running (docker)
redis                     running (docker)
mysql                     running (docker)
scrapyd1                  running (docker)
scrapyd2                  running (docker)
scrapyd3                  running (docker)
dev                       running (docker)

Now I can connect to dev with sudo vagrant ssh dev:

$ sudo vagrant ssh dev
root@dev:~# cd book/
root@dev:~/book# ls
ch03  ch05  ch07  ch09  ch11                insecure_key  README.md    Vagrantfile.32          Vagrantfile.dockerhost.src
ch04  ch06  ch08  ch10  docker-compose.yml  lint          Vagrantfile  Vagrantfile.dockerhost

Then I can shut it down with sudo vagrant halt:

$ sudo vagrant halt
==> dev: Stopping container...
==> scrapyd3: Stopping container...
==> scrapyd2: Stopping container...
==> scrapyd1: Stopping container...
==> mysql: Stopping container...
==> redis: Stopping container...
==> es: Stopping container...
==> spark: Stopping container...
==> web: Stopping container...

Now everything should be stopped:

$ sudo vagrant status
Current machine states:

web                       stopped (docker)
spark                     stopped (docker)
es                        stopped (docker)
redis                     stopped (docker)
mysql                     stopped (docker)
scrapyd1                  stopped (docker)
scrapyd2                  stopped (docker)
scrapyd3                  stopped (docker)
dev                       stopped (docker)

After doing it once, now, it should always work and be fast to start/stop.

It works beautifully! Thanks a ton. One line change "force_host_vm = FALSE" made all the difference.
