Keep files in `/bin` & change the log-in user

Hi @ailispaw , I have two questions.

  1. I want to save a file in /bin. However, the file will be removed after vagrant halt && vagrant up or vagrant reload. Are there any ways to keep files in /bin?
  2. What's the easiest way to change the log-in user?

Hi @ixkaito,

  1. You can use /opt/bin instead.
    /opt, /home and /etc are persistent.
  2. You can override the user by setting config.ssh.username and so on.
    Cf.) https://docs.vagrantup.com/v2/vagrantfile/ssh_settings.html

$ vagrant ssh
Welcome to DockerRoot version 1.2.5, Docker version 1.9.1, build a34a1d5
[docker@docker-root ~]$ sudo adduser -h /home/ailispaw -s /bin/bash -G docker ailispaw
[docker@docker-root ~]$ sudo sudo cp -r ~/.ssh/ /home/ailispaw
[docker@docker-root ~]$ sudo chown -R ailispaw /home/ailispaw/.ssh
[docker@docker-root ~]$ exit

Add config.ssh.username = "ailispaw" into Vagrantfile

$ vagrant ssh
Welcome to DockerRoot version 1.2.5, Docker version 1.9.1, build a34a1d5

Thanks!

/opt/bin works well after vagrant ssh. However, if I don't log in or execute my command in the provisioning, it will be not found.

$ vagrant ssh -- mycommand
bash: mycommand: command not found

config.ssh.username works after the first vagrant up. If I want to use another user than docker at the first vagrant up, I have to build my own box, haven't I?

Try vagrant ssh -c 'yourcommand'.

Yes.
Just curious, what do you need an another user for?

ailispaw commented

Oh, you are right. > bash: mycommand: command not found
I will figure this out.

ailispaw commented

I got it.
/opt/bin is set into PATH when a user is in login shell but just shell.
The ailispaw/docker-root box has config.ssh.shell = "bash", not "bash -l".

You have some options for now.

  1. Add config.ssh.shell = "bash -l" into your Vagrantfile and vagrant ssh -c 'yourcommand'.
  2. vagrant ssh -c 'bash -l -c "yourcommand"'
  3. vagrant ssh -c '/opt/bin/yourcommand'

I will consider how I can fix this issue in the box.
Thanks.

Never mind. This is not important. I just wanted to change it to my project name if I could do it easily.

v1.2.6 works perfectly! Many thanks. I will release a major update of my project 'Wocker' using DockerRoot in a few days:)
