Docker

Gitea is great when you want a fast, light and yet user-friendly git repositories. Alternatives would be Gogs, Gitlab or even Github. Gitea documentation tells you to use docker exec to perform a backup. However, this prevents you from using an additional volume to dump the backup into. Instead, I prefer to use a similar command using docker run. Assuming the following: the container network is called gitea_default, you only need this if you use an external database such as MySQL the container is called gitea the backup directory is in the current directory and named backups docker run --rm -it --network gitea_default --volumes-from gitea --volume $(pwd)/backups:/backups --user git --workdir /backups --entrypoint '/app/gitea/gitea' gitea/gitea:1....

Recently, I had to set up a new PKI. I was going to go with the good old OpenSSL but it’s 2021, there must be a more userfriendly and, more importantly, automated approach. There are many open-source possibilities: EJBCA, cfssl, Hashicorp Vault, Smallstep Certificates. I chose to use Smallstep certificates because it has all the features I need and they are not behind a pay-wall: lightweight: small Go binary, you can run it with a file-based database (similar to SQLite) user friendly CLI: compared to openssl commands ACME protocol: useful for Traefik reverse proxy OIDC authentication support: the guys are super friendly and available on their Discord channel Be sure to check their website, they have other features that you might want, especially their Certificate Manager....

After reading many articles and trying many things, this is how I solved it. For docker daemon itself to use a proxy, configure environment variables using systemd file /etc/systemd/system/docker.service.d/http-proxy.conf : [Service] Environment="HTTP_PROXY=http://user:pass@proxy.domain.com:3128/" Environment="HTTPS_PROXY=http://user:pass@proxy.domain.com:3128/" Environment="NO_PROXY=localhost,docker,*.domain.com" For gitlab-runner daemon itself to use a proxy, configure environment variables using systemd file /etc/systemd/system/gitlab-runner.service.d/http-proxy.conf : [Service] Environment="HTTP_PROXY=http://user:pass@proxy.domain.com:3128/" Environment="HTTPS_PROXY=http://user:pass@proxy.domain.com:3128/" Environment="NO_PROXY=localhost,docker,*.domain.com" Reload systemd and restart docker daemon: systemctl daemon-reload systemctl restart docker For git commands run by gitlab-runner to use a proxy, use gitlab-runner config file....
