GitLab CI: Mein Testjob übernimmt den mysql Container nicht

Question

Ich habe eine Springboot-Anwendung, die mit einer MySQL-Datenbank verbunden ist. Ich möchte die .gitlab-ci.yml verwenden, um die Pipeline zu behandeln. Ich habe die folgende Konfigurationsdatei erstellt.

before_script: 
- echo "Execute scripts which are required to bootstrap the application. !" 

after_script: 
- echo "Clean up activity can be done here !." 

services: 
- mysql 

stages: 
- build 
- connect 
- test 
- package 
- deploy 

variables: 
MAVEN_CLI_OPTS: "--batch-mode" 
MAVEN_OPTS: "-Dmaven.repo.local=.m2/repository" 
MYSQL_DATABASE_NAME: gyyconsortiumdb 
MYSQL_DATABASE_SCHEMA: "$CI_PROJECT_DIR/src/main/resources/static/sql/gyyconsortiumdb.sql" 
MYSQL_ROOT_PASSWORD: mysql 

cache: 
paths: 
    - .m2/repository/ 
    - target/ 

build: 
stage: build 
image: maven:latest 
script: 
    - mvn $MAVEN_CLI_OPTS clean compile 

connect: 
stage: connect 
image: mysql 
before_script: 
    - mysql --version 
script: 
    - echo "create database $MYSQL_DATABASE_NAME;" | mysql --user=root --password="$MYSQL_ROOT_PASSWORD" --host=mysql 
    - mysql --user=root --password="$MYSQL_ROOT_PASSWORD" --host=mysql $MYSQL_DATABASE_NAME < $MYSQL_DATABASE_SCHEMA 
    - mysql --user=root --password="$MYSQL_ROOT_PASSWORD" --host=mysql -e "show databases; use $MYSQL_DATABASE_NAME; show tables;" 

test: 
stage: test 
image: maven:latest 
script: 
    - mvn $MAVEN_CLI_OPTS test 

package: 
stage: package 
image: maven:latest 
script: 
    - mvn $MAVEN_CLI_OPTS package 
artifacts: 
    paths: [target/basecamp-0.0.1.war] 


deploy_test: 
stage: deploy 
script: 
- echo "######## To be defined ########" 
environment: staging 

deploy_prod: 
stage: deploy 
script: 
    - echo "######## To be defined ########" 
only: 
    - master 
environment: production 

Wenn der erste Auftrag läuft, es zieht das mysql Bild von Docker-Hub, und ich weiß nicht, warum? Ich dachte, dass die mysql nur auf dem Verbindungsjob gebaut werden sollte.

Nachdem der Verbindungsjob erfolgreich ist, zieht der Testjob das mysql-Image erneut an. Und mein Testjob erkennt meine Datenbank nicht, aber der Dienst wurde erfolgreich erstellt und ich konnte sehen, dass die Datenbank auch erstellt wurde.

Könnten Sie mir bitte sagen, warum der Test Job nicht von Pick up den mysql-Dienst den richtigen Weg?

Best, G

Answer 1

Wenn der erste Auftrag ausgeführt wird, wird das mysql Bild von Docker Nabe ziehen, und ich weiß nicht, warum?

Weil Sie Mysql als Service definiert. GitLab CI verwendet das Schlüsselwort services, um festzulegen, welche Andockcontainer mit Ihrem Basisimage verknüpft werden sollen. Also wird es für jede Stufe ausgeführt.

Könnten Sie mir bitte sagen, warum der Testjob den mysql Dienst nicht richtig aufnimmt?

Ihre Datenbanknamen in Ihrer Gitlab Konfigurationsdatei ist ‚gyyconsortiumdb‘, die sich von dem unterscheidet, was Sie in Ihrer Feder-Konfigurationsdatei als log definiert zeigt Ihnen

jdbc4.MySQLSyntaxErrorException zu ‚mydb‘ zu verbinden versuchen: unbekannte Datenbank 'mydb'
