Flock 2016: my notes
Last week we were at Flock 2016 which was held in Krakow, Poland. Awesome event, lots of news, great people, plenty of conversations and fun.
Here is a list of my notes:
…Automatic mounts with systemd
So I wanted to setup automatic mounting (read as autofs) with systemd, without using fstab.
Unfortunately, the man page didn’t have any examples so it wasn’t that easy to figure out. Luckily there is an excellent guide at RHCSA course [1].
Tl;dr
…Tips and tricks to write Dockerfiles
After my yesterday talk at DevConf 2016 I got asked about some tips and tricks how to write Dockerfiles. I know we have plenty of resources for that in Red Hat, Fedora and Project Atomic. So, here we go!
…Copy your private GPG key to a new machine
It’s really simple to copy your private GPG keys to another machine of yours. Let’s do public key first: $ gpg --export --armor KEY | ssh me@my-other-machine 'gpg --import' gpg: keyring `/home/me/.gnupg/secring.gpg' created gpg: keyring `/home/me/.gnupg/pubring.gpg' created gpg: /home/me/.gnupg/trustdb.gpg: trustdb created gpg: key 4937B925: public key "KEY" imported gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1) It worked! Now the private: $ gpg --export-secret-key --armor KEY | ssh me@my-other-machine 'gpg --import --allow-secret-key-import' gpg: key 4937B925: secret key imported gpg: key 4937B925: "KEY" not changed gpg: Total number processed: 1 gpg: unchanged: 1 gpg: secret keys read: 1 gpg: secret keys imported: 1 (--armor is optional, it’s just for sake of checking the output first before piping it to ssh)…
Build docker engine on Fedora
It’s not that hard, here are a couple pain points:
- make sure that
GOPATHis right — you want to compile against your checked out docker, not master docker
Running chromium in docker container
I’ve just managed to dockerize chromium. The package itself is taken from spot’s copr repo. Jessie Frazelle’s blog post helped me a lot!
It looks like this:
…Compiling kernel on gentoo
I’ve just updated to kernel 3.17. I compiled the kernel, installed it, generated initramfs, updated grub.cfg and rebooted my PC. I was unpleasantly surprised by:
