Unable to setup liquibase using docker image

Hello,

I’m using below command to generate changelog.
however the changelog.xml in /root/liquibase/changelog is empty.

{code}

docker run -v /root/liquibase/changelog:/liquibase/changelog liquibase:4.3.5 --classpath=/liquibase/changelog --url=“jdbc:mysql://10.x.x.x:3306/testdb?useSSL=FALSE” --driver=“com.mysql.cj.jdbc.Driver” --username=“username” --password=‘password’ --changeLogFile=changelog.xml generateChangeLog

Hi @lq-user

I haven’t tried this but may be you could give this a try and check if this helps.
Try using options:
--includeSchema=true and --schemas=your_schema_name
in your generateChangelog command. These options works in PostgreSQL DB for me.

Please let us know the results.

Thanks!

Thanks @rakhi

the container exits immediately , hence i don’t know where to check the changelog file contents

Any suggestions?

docker run --rm -v /root/liquibase/changelog:/liquibase/changelog liquibase:4.3.5 --url=“jdbc:mysql://10.x.x.x:3306/dbname” --driver=“com.mysql.cj.jdbc.Driver” --username=“username” --password=‘password’ --defaultSchemaName=performance_schema --changeLogFile=test.xml --logLevel INFO --includeSchema=true --schemas=dbname generateChangeLog

You can check the contents inside /liquibase/changelog volume I think. I have never really run liquibase with docker so can’t guarantee this.

But I found something which will help get the file created on local. This can help you confirm if the file has correct contents. Please read this doc.

If you have a local c:\projects\my-project\src\main\resources\com\example\changelogs\root.changelog.xml file, you can run:

docker run --rm -v c:\projects\my-project\src\main\resources:/liquibase/changelog 
--changeLogFile=com/example/changelogs/root.changelog.xml update

Hope this helps in some way.

Thanks,

Why does these two outputs differ:

docker run --rm -v /root/liquibase/changelog:/liquibase/changelog liquibase:4.3.5 --url=“jdbc:mysql://10.x.x.x:3306/dbname” --driver=“com.mysql.cj.jdbc.Driver” --username=“username” --password=‘password’ --defaultSchemaName=performance_schema --changeLogFile=test.xml --logLevel INFO --includeSchema=true --schemas=dbname generateChangeLog

*changeLogFile path is changed

I’ll suggest to try out the local copy of file once as I mentioned in one of the replies earlier. Let’s check what exactly are the contents of file.

With your second trial it seems it’s not able to create test.xml because of permission issues. However as you have tried in the first trial, it was able to find atleast some contents to be populated inside resultant changelog file and was able to create a test.xml file when it didn’t exist.

can you please eloboarte on the local file part?

when i tried to not use any path for changelogfile , its success but i cant find the file local nor in the container

eg:

docker run --rm -v /root/liquibase/changelog:/liquibase/changelog liquibase:4.3.5 --url=“jdbc:mysql://10.x.x.x:3306/dbname” --driver=“com.mysql.cj.jdbc.Driver” --username=“username” --password=‘password’ --defaultSchemaName=performance_schema --changeLogFile=.test.xml --logLevel INFO --includeSchema=true --schemas=dbname generateChangeLog

BEST PRACTICE: The changelog generated by diffChangeLog/generateChangeLog should be inspected for correctness and completeness before being deployed.
[2021-06-03 07:14:06] INFO [liquibase.diff] changeSets count: 3
[2021-06-03 07:14:06] INFO [liquibase.diff] .test.xml does not exist, creating and adding 3 changesets.
Liquibase command ‘generateChangeLog’ was executed successfully.

so issue is with permissions

i tried with user root option

docker run –user root -v …–changeLogFile=/liquibase/changelog/test.xml … generateChangeLog

inside the container

$ cd changelog
