Change docker root directory by creating a systemd drop-in service file

Filed under: Linux — Tags: , , — admin @ 2:20 pm

 It is possible to change docker root directory by creating a systemd drop-in service file. This is useful when you want images and containers or docker generated files to be located in another partition or drive.

Create drop-in configuration file

  1. Create the systemd directory:
    sudo mkdir /etc/systemd/system/docker.service.d/
  2. Create the docker.service drop-in file:
    sudo nano /etc/systemd/system/docker.service.d/docker.root.conf
  3. Add the following configuration :
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -g /your/custom/docker/root -H fd://

Ubuntu 18 imagemagick convert: not authorized

Filed under: Linux — Tags: , , , — admin @ 7:01 pm

Well on ubuntu 18 try to convert some pdf error

convert: not authorized /pdf/original/70/5770.pdf' @ error/constitute.c/ReadImage/412. convert: no images defined/pdf/processed/70/5770.jpg’ @ error/convert.c/ConvertImageCommand/3258.

The solution is to modify the /etc/ImageMagick-6/policy.xml

At the end this

domain=”coder” rights=”none” pattern=”PDF”

Into this

domain=”coder” rights=”read|write” pattern=”PDF”

pdftk ubuntu 18

Filed under: Linux — Tags: , — admin @ 6:22 pm

Today I have tried to install pdftk on ubuntu 18 . After search on developer site I saw that are package only for the redhat/centos.

So after a few search find out that you can install it with snap install pdftk

However this will not work .

Error: Unable to find file.
Error: Failed to open PDF file:
Errors encountered. No output created.
Done. Input errors, so no output created.

Errors like this you will see.

One solution is to download and install from other links

cd /tmp
# download packages
wget http://launchpadlibrarian.net/340410966/libgcj17_6.4.0-8ubuntu1_amd64.deb \
 http://launchpadlibrarian.net/337429932/libgcj-common_6.4-3ubuntu1_all.deb \
 https://launchpad.net/ubuntu/+source/pdftk/2.02-4build1/+build/10581759/+files/pdftk_2.02-4build1_amd64.deb \
 https://launchpad.net/ubuntu/+source/pdftk/2.02-4build1/+build/10581759/+files/pdftk-dbg_2.02-4build1_amd64.deb

And after that you can install them with 
sudo apt-get install ./libgcj17_6.4.0-8ubuntu1_amd64.deb \
    ./libgcj-common_6.4-3ubuntu1_all.deb \
    ./pdftk_2.02-4build1_amd64.deb \
    ./pdftk-dbg_2.02-4build1_amd64.deb

After that you can remove those from /tmp directory
