Prototyping latest Alfresco on Docker on CentOS 7

Jump to solution

I've managed to start latest Alfresco on Docker on CentOS 7.

I have plenty of experience in Alfresco environment in old fashioned way, but zero in the new reality so be kind to me. Smiley Happy

So, this is dockered Alfresco, and I'd like to do some prototyping in developing some test web scripts.

How do I do it, for example in Eclipse dev environment?

TIA!

I did it finally!

Several things were wrong in my setup, so it may help some unfortunate soul:

1. Your DB URI/name is not "localhost" or "127.0.0.1", but how you name it in your docker-compose file. My DB:

   database:
        image: mysql:5.7
        mem_limit: 512m

...

2. Wherever you reference DB, use that name, for example in alfresco service in docker-compose,yml file:

JAVA_OPTS
...
-Ddb.url=\"jdbc:mysql://database:3306/alfresco?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&useSSL=true\"

In YOUR OWN alfresco-global.properties file:

##
# MySQL
##
db.name=alfresco
db.username=alfresco
db.password=alfresco
db.driver=com.mysql.cj.jdbc.Driver
db.url=jdbc:mysql://database/${db.name}?useUnicode=true&characterEncoding=UTF-8
db.master.url=jdbc:mysql://database/
db.master.username=${db.username}
db.master.password=${db.password}
db.drop.command=drop database if exists ${db.name}
db.create.command=create database ${db.name} CHARACTER SET utf8 COLLATE utf8_bin;

2. Volumes for alfresco service (watch out for writing permissions if on Linux!):

        volumes:
           - ./volumes/data/alf_data:/usr/local/tomcat/alf_data
           - ./mysql-connector-java-8.0.25.jar:/usr/local/tomcat/lib/mysql-connector-java-8.0.25.jar
           - ./alfresco-global.properties:/usr/local/tomcat/shared/classes/alfresco-global.properties

3. My complete database service (with volumes):

    database:
        image: mysql:5.7
        mem_limit: 512m
        environment:
            - MYSQL_ROOT_PASSWORD=root
            - MYSQL_DATABASE=alfresco
            - MYSQL_USER=alfresco
            - MYSQL_PASSWORD=alfresco
        command: --explicit_defaults_for_timestamp
        ports:
            - 3306:3306
        security_opt:
            - seccomp:unconfined
        cap_add:
            - SYS_NICE  # CAP_SYS_NICE
        volumes:
        - ./volumes/data/mysql_data:/var/lib/mysql
        - ./volumes/logs/mysql:/var/log/mysql

I'm happy, officially! Smiley Happy

Yes, that's heavy on the web scripts developing with Maven and creating AMPs, what I'm the most interested is the part of Docker deployment of AMPs on dockered Alfresco, to be precise on Alfresco in docker-compose. I'm as a babe regarding Docker and docker-compose, I need baby food. Smiley Happy

You can use this project:

https://github.com/alfresco/alfresco-docker-installer

Just copy your AMPS / JARS to the "modules" folder and it's done.

One of dockers in this compose is Postgres as a DB. How can I change it into MySQL?

Re: Prototyping latest Alfresco on Docker on CentOS 7

I guess you can choose also in alfresco-docker-installer using MySQL / MariaDB. You can change it in order to understand how that works.

Re: Prototyping latest Alfresco on Docker on CentOS 7

Jump to solution

I've tried with in yml:

alfresco:

...

JAVA_OPTS: "
-Ddb.driver=com.mysql.jdbc.Driver
-Ddb.username=alfresco
-Ddb.password=alfresco
-Ddb.url=jdbc:mysql://localhost:3306/alfresco

 

mysql:
image: mysql:8
mem_limit: 512m
environment:
- MYSQL_ROOT_PASSWORD=root
- MYSQL_DATABASE=alfresco
- MYSQL_USER=alfresco
- MYSQL_PASSWORD=alfresco
command: --default-authentication-plugin=mysql_native_password
ports:
- 3306:3306

But there's a problem with solr6, according to log. Maybe I should try with another MySQL image.

Edit:

I tried to downgrade MySQL to 5.7, but still the same error. I still haven't found where docker-compose log is, I can see only stack traces flying in the terminal, but I think I saw alfresco and solr docker images can't find MySQL driver. If that is the case, how and where can I put the MySQL driver?

This is for MariaDB, found your way for MySQL:

I've managed to inject CNF file for MySQL and a MySQL connector JAR in alfresco lib folder, but I still get an error:
