install docker in debian jessie without unnecessary cgroupsfs-mount, mountall, and plymouth dependencies

docker

Install docker on your debian jessie workstation without unnecessary cgroupsfs-mount, mountall, and plymouth recommended dependencies.

Reference: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=783143

Prerequisite: jessie-backports. Configure jessie-backports or the riskier unstable “sid” repositories before proceeding.

sudo aptitude install aufs-tools libnih-dbus1 libnih1 makedev git
sudo aptitude install -t jessie-backports --without-recommends docker.io

This should work, but be aware aptitude show docker.io shows these are required also:

Depends: adduser, iptables, init-system-helpers (>= 1.18~), perl, libapparmor1 (>= 2.6~devel),
 libc6 (>= 2.14), libdevmapper1.02.1 (>= 2:1.02.90), libsqlite3-0 (>= 3.5.9)

Now add your user account to the docker group; otherwise you will receive the error “permission denied. Are you trying to connect to a TLS-enabled daemon without TLS?”

sudo gpasswd -a $USER docker ( same as sudo usermod -a -G docker $USER)

Logout and re-login. Potentially, you could also exec su -l $USER

Now start docker and set it enabled by default.

sudo systemctl enable docker
sudo systemctl start docker

Now install your preferred containers

docker pull vmware/powerclicore

Docker : "permission denied. Are you trying to connect to a TLS-enabled daemon without TLS?"

docker

Docker : “permission denied. Are you trying to connect to a TLS-enabled daemon without TLS?”, when docker pull

solution: add username to group docker, logout and relogin ; make certain the service is running

sudo groupadd docker
sudo gpasswd -a $USER docker (same as sudo usermod -a -G docker $USER)

Logout and re-login. Potentially, you could also exec su -l $USER

sudo cystemctl start docker
sudo cystemctl enable docker #if you want it enabled by default

persistent powershell commandline history

PowerShell

Persistent PowerShell CommandLine History

via https://github.com/lzybkr/PSReadLine (& https://technet.microsoft.com/en-us/library/bb613488(v=vs.85).aspx)

TL;DR :
Win10 install module:
Install-Module PSReadline

edit* system’s powershell profile:
notepad c:\windows\system32\WindowsPowerShell\v1.0\profile.ps1

to the end of the file, add:
Import-Module PSReadline

restart powershell

*(never use notepad, use https://www.sublimetext.com/ + https://packagecontrol.io/ instead)
