golang continuous deployment & gitlab

[Sankar]

Hi

I have a golang HTTP server that I am deploying on an AWS EC2 VM, as a systemd service.

Right now, I am manually deploying the service as follows:

1) vm$  sudo systemctl stop <myservice>

2) dev$ scp <cross-compiled-binary-from-dev-laptop> <vm>

3)psql$ Apply migrations manually

4) vm$  sudo stystemctl start <myserver>

4) vm$  sudo stystemctl status <myserver> ;# Just to check

I maintain my sources in gitlab and my database is postgres.

I am planning to use gitlab-ci for preparing cross-compiled systemd binaries and also sqitch for postgres migrations.

I wanted to ask if there are any advises (or links to tools/blogposts/scripts) from existing gitlab (or even github+ci) + golang users, who do continuous deployments already. I can have some downtime and 100% uptime is not important for me. Also, one instance of my server is enough and there is no need for HA, load-balancing, etc. as of now, as it is just an internal low-traffic service.

I also thought of preparing an ubuntu ppa repository internally, on the lines of https://about.gitlab.com/2016/10/12/automated-debian-package-build-with-gitlab-ci/

I am not using Docker (containers) because I do not want another layer which may cause some unknown problems (performance, networking, etc.) which I do not want to end up debugging.

Any advises or suggestions or links that would help me ? Thanks.

Hi,

At work we have all of our deployment logic written in ansible and simply call an ansible playbook from jenkins (gitlab-ci in your case)

Here is a sample project using ansible

https://github.com/fmpwizard/mrwilson/tree/master/ansible

it has all the roles, code, etc needed to start with a fresh fedora server provided by digital ocean (so bare that it starts by installing python using the raw command and then continues to use regular ansible code)

This file:

https://github.com/fmpwizard/mrwilson/blob/master/ansible/all_roles.sh

shows you the commands your ci would run, depending on what you need.

this deploys the binary:

ansible-playbook -i hosts/production playbooks/deploy.yml --ask-vault-pass -u root

and after it is deployed,

ansible-playbook -i hosts/production playbooks/site-state.yml --ask-vault-pass --extra-vars "app_state=restart" -u root

restarts systemd

No docker in this setup,

Hope it helps.

Diego
