Problems running '/nextdocker.yml'

[Gerry33]

Hi Reiner, thanks for this nice setup and the efforts on your work. Unfortunately I don't get it to work, so I kindly ask for some assistance.

After struggling with of problems on the python setup, I finally managed to get 'ansible' working. It reports:

ansible --version
ansible 2.8.6
  config file = /home/xxx/programs/nextcloud_on_docker/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/lib/python2.7/dist-packages/ansible
  executable location = /usr/local/bin/ansible
  python version = 2.7.15+ (default, Oct  7 2019, 17:39:04) [GCC 7.4.0]

Is that correct ?

When running ansible playbook '/nextdocker.yml', it fails with error messages:

I do not have iptables installed. I'm running a bare blank server edition of:

NAME=Ubuntu
    ++ VERSION='18.04.3 LTS (Bionic Beaver)'
    ++ ID=ubuntu
    ++ ID_LIKE=debian
    ++ PRETTY_NAME='Ubuntu 18.04.3 LTS'
    ++ VERSION_ID=18.04

on an ODROID C2 which reports its hardware Linux server 3.16.72-46 #1 SMP PREEMPT Tue Aug 13 18:09:58 -03 2019 aarch64 aarch64 aarch64

BTW, does your setup need 'docker-compose' as an executable as this is not present in the official docker repositories for arm64/aarch64 ?

Thanks for any help ! Gerd

If you don't want/need a firewall just comment out this line: https://github.com/ReinerNippes/nextcloud_on_docker/blob/f95ff0cf71cc4cd3d4905d8c9dfc22b64d6e10a2/nextdocker.yml#L8

and there is another include_role: ufw in roles\talk\tasks\main.yml that needs to be disabled if you want to install talk.

docker-compose is not needed. the playbook is a kind of replacement to docker-compose.

Hi Reiner, thank your very much for your fast response. It worked ....

But immediately followed by the next blocker:

Although I'm a bit familiar with Linux, I never heard of 'Starting Disable Transparent Huge Pages.'

Edit1: Found this: https://unix.stackexchange.com/questions/99154/disable-transparent-hugepages Tried apt install hugepages' && hugeadm --thp-never but 2nd failed: hugeadm:ERROR: Couldn't open /sys/kernel/mm/transparent_hugepage/enabled: No such file or directory

Edit2: My 'hugepages' are named different: /sys/kernel/mm/hugepages/hugepages-2048kB/

Shall I try to change that in your setup ? # But where ?

Again, thanks for taking care. Gerd

but you may try first on the cli if it's working anyway. i think on odroid it might not be a big deal anyhow.

Hi Reiner, and thanks for response.

One step ahead, but then again a big blocker , where I will now give up here. The docker daemon will not even start, so its time to finish this here.

Again thanks for your efforts and have a nice remaining sunday. Gerd

[ReinerNippes]

may you can use the docker version from your ubuntu droid distro.

change to state: present

https://github.com/ReinerNippes/nextcloud_on_docker/blob/dd93e8ea9ce62dc4d08ba5ecc88cf3086797eb20/roles/prep_docker/tasks/Ubuntu.yml#L10

choose the name of the docker package. (apt-cache search docker - remove the docker.com repo in /etc/apt/source.list.d first) and delete the rest of file Ubuntu.yml

[Gerry33]

Thansk, I wil give it a try.

I used to install Docker this way:

curl -fSSl https://get.docker.com -o docker.sh
chmod +x docker.sh
sudo ./docker.sh

Will try to get it done this way.
