This is the second post regarding basic configuration of Raspberry Pi 2.

    Timezone change

    By default, Raspberry Pi 2 will use UTC time. Command tzselect will give you continent and country selection to pick.

    [email protected] ~ $ tzselect
    Please identify a location so that time zone rules can be set correctly.
    Please select a continent or ocean.
     1) Africa
     2) Americas
     3) Antarctica
     4) Arctic Ocean
     5) Asia
     6) Atlantic Ocean
     7) Australia
     8) Europe
     9) Indian Ocean
    10) Pacific Ocean
    11) none – I want to specify the time zone using the Posix TZ format

    Add Cron Job

    Add a cron job to halt Raspberry Pi at 23:00 everyday.

    [email protected] ~ $ crontab -e

      GNU nano 2.2.6           File: /tmp/crontab.obWc51/crontab                          

    # Edit this file to introduce tasks to be run by cron.
    #
    # Each task to run has to be defined through a single line
    # indicating with different fields when the task will be run
    # and what command to run for the task
    #
    # To define the time you can provide concrete values for
    # minute (m), hour (h), day of month (dom), month (mon),
    # and day of week (dow) or use ‘*’ in these fields (for ‘any’).#
    # Notice that tasks will be started based on the cron’s system
    # daemon’s notion of time and timezones.
    #
    # Output of the crontab jobs (including errors) is sent through
    # email to the user the crontab file belongs to (unless redirected).
    #
    # For example, you can run a backup of all your user accounts
    # at 5 a.m every week with:
    # 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
    #
    # For more information see the manual pages of crontab(5) and cron(8)
    #
    # m h  dom mon dow   command
    0 23 * * * sudo halt

    Install Portainer

    Assume you have installed HypriotOS from https://ift.tt/36gAWgF
    Docker and Docker-Compose has been installed. The default credentials for the image are user pirate with password hypriot.

    You always can change it from raspi-config menu.

    Check docker version and docker-compose version.
