Использую стандартный шаблон проекта
Node.js+Express.
Работаю в ветке
dev.
После комита запускается Auto DevOps и создаётся контейнер.
Он заливается в Gitlab Container Registry, сейчас там
0 штук.
Успешно выполняется build из файла
Build.gitlab-ci.yml.
Для билда вызывается этот скрипт:
/build/build.sh#!/bin/bash -e
# build stage script for Auto-DevOps

Контейнер появился:
Запускаю его на VPS (порт 27073):
sudo docker run -d -p $PUBLIC_PORT:5000 $CI_REGISTRY_IMAGE/$CI_COMMIT_BRANCH:latest
Проверяем, что контейнер запущен:
user@instance:~$ sudo docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS
7258f2b4b44c registry.gitlab.com/company/project/dev:latest "docker-entrypoint.s…" 55 seconds ago Up 42 seconds 0.0.0.0:27073->5000/tcp, :::27073->5000/tcp
Проверяем, что он возвращает:
user@instance:~$ curl http://localhost:27073
<!DOCTYPE html><html><head><title>Express</title><link rel="stylesheet" href="/stylesheets/style.css"></head><body><h1>Express</h1><p>Welcome to Express</p></body></html>
Всё верно, отображается приветствие
Express.
Теперь в файле index.js заменяю строку на
Express 2:
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express 2' });
});
Выполняю все предыдущие шаги, появляются ещё один контейнер:
На VPS удаляю старый контейнер.
Запускаю новый (см. колонку CONTAINER ID).
user@instance:~$ sudo docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS
d841d98c026b registry.gitlab.com/rolesuhub/node/dev:latest "docker-entrypoint.s…" 35 seconds ago Up 23 seconds 0.0.0.0:27073->5000/tcp, :::27073->5000/tcp
Но он отображает старую надпись
Express.
user@instance:~$ curl http://localhost:27073
<!DOCTYPE html><html><head><title>Express</title><link rel="stylesheet" href="/stylesheets/style.css"></head><body><h1>Express</h1><p>Welcome to Express</p></body></html>
Ожидаем надпись
Express 2.
Что я сделал не так?
Простой
Сложный
