Hi there,
I revived my BananaPi M1 (ARM7 32bit) last week. I installed a fresh armbian and just docker like this:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian \
$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
sudo gpasswd -a $USER docker
newgrp docker
docker run hello-world
The "Hello world" worked.
But when I tried to run anything useful things failed. Seafile installed okay, but calling the UI timed out. Paperless-ngx complained that paperless-webserver cannot find route to redis. Stuff like this. I just want to use the machine in my internal Network at home.
To investigate further I installed a simple httpd docker to see if I can reach that one. No luck. Neither from another machine in my LAN, nor via lynx on BananaPi calling localhost. The request goes out as the port seems to be open, but it never reaches the daemon inside the container or cannot respond. Same commands on my "production box" (a HP t630 with debian bookworm) work fine.
So my conclusion is that it must be something in the OS.
I compared iptables on BananaPi and t630 and checked the output of 'sudo /usr/sbin/sysctl -a | grep forwarding | grep ipv4' - they are the same.
I'm a little bit clueless where to check, what commands to use as I'm quite new to docker. Do you have any suggestions?
Thanks, Peter.
