check this migration guide https://github.com/revant/frappe_docker/blob/refactor-single-image/docs/migrate-from-multi-image-setup.md

Anyone can test this using frappe/erpnext:v14.11.1 image.

[revant]

I'll merge by next week. It'll be easier for me to maintain it.

[revant]

https://github.com/revant/frappe_docker/blob/refactor-single-image/docs/custom-apps.md#load-custom-apps-through-json

should the Apps json be base64encoded string?
easy to move around without causing character escape issues.
json looks simple but simplicity can be achieved by piping json to base64 and passing that to build-arg.

anyone?

anyone?

I would say it should probably be a json file for readability and not be base64 encoded

Would there be a way to maintain both?

[revant]

not really.

[revant]

I made it BASE64 string. It was failing for cases where git token/password had # in it. Need something that is environment variable friendly

It is used like this:

mkdir /opt/frappe && echo "${APPS_JSON_BASE64}" | base64 -d > /opt/frappe/apps.json;

For readability

export APPS_JSON='[
  {
    "url": "https://github.com/frappe/payments",
    "branch": "develop"
  },
  {
    "url": "https://github.com/frappe/erpnext",
    "branch": "version-14"
  },
  {
    "url": "https://user:password@git.example.com/project/repository.git",
    "branch": "main"
  }
]'
export APPS_JSON_BASE64=$(echo ${APPS_JSON} | base64 --wrap=0)

Now you can even create a file /path/to/apps.json and feed it like export APPS_JSON_BASE64=$(cat /path/to/apps.json | base64 --wrap=0)

[revant]

It will be easy to build version-12, version-13 and version-14 apps. I tried building all version successfully.
anyone who is facing any asset builder issue or asset population issue this will solve it.

Frontend container has contained assets for it to serve. Backend and workers have the assets in case they require them, even socketio will have them if needed in future or in custom apps. There is no need for re-population of assets because the container gets its own assets.

@sdfateh @lekhnath do try with your version 13 custom apps.

[sdfateh]

@revant

I think we should give that more time, in order to do experiments and approval. A slight effect on production could eliminate the idea of ​​using a container.

I really appreciate your effort, but please keep it slow.

[revant]

how much more time is enough?

[sdfateh]

@revant
I think it's not about time, it's about testing and verifying.

[sdfateh]

I have this error with frontend now :

Error response from daemon: Cannot restart container 91cf090169f2404a9d69d7d6a5b7aab6fb5aab86c1e21ed23ec1da1c314ab08c: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "nginx-entrypoint.sh": executable file not found in $PATH: unknown

Any advice ?

[revant]

• is nginx-template.sh it in path? exec into container and find out. docker run --rm -it frappe/erpnext:v14.11.1 which nginx-entrypoint.sh
• It needs to get copied, it needs to be executable, it needs to be in path.

Confirm build arch as well, sometimes scripts don't execute if image is pulled for different arch.

[sdfateh]

@revant

I added :

RUN chmod 755 /usr/local/bin/nginx-entrypoint.sh

to my dockerfile to have the x permission to scripts ,
I see that your image script has x permissions to the scripts but in the dockerfile no chmod

any advice?

[revant]

any advice?

All the devices I use are linux based. May be it preserves the permission for me on git clones. Also in cluster/kaniko executor it pulls as linux and preserves permission.

Is there a way you can chmod +x nginx-entrypoint.sh on your local machine and then build?

[sdfateh]

I solved it for me by adding RUN chmod 755 /usr/local/bin/nginx-entrypoint.sh to the Dockerfile,
So I just ask you for your opinion, If we have to add it to the dockerfile let us edit the PR and add it.

@revant

[revant]

So I just ask you for your opinion, If we have to add it to the dockerfile let us edit the PR and add it.

As you're telling me to add, I'll add a RUN layer with chmod. only that? anything else?

you can add review on GitHub? that way i can resolve one by one. you're the only expert who is commenting, may be after you add review others will also add their review.

[sdfateh]

@revant What do you mean by review on GitHub, A new issue on this repo, or on the PR?

[sdfateh]

I have another problem, after using the new one image, something important changed in the MariaDB,
When creating sites on the old way, that is user list:

MariaDB [(none)]> select host, user from mysql.user;
+-----------+-------------+
| Host      | User        |
+-----------+-------------+
| %         | devops1     |
| %         | root        |
| localhost | mariadb.sys |
| localhost | root        |
+-----------+-------------+
4 rows in set (0.002 sec)

But in the new it is like this:

MariaDB [(none)]> select host, user from mysql.user;
+--------------+-------------+
| Host         | User        |
+--------------+-------------+
| %            | root        |
| 10.10.104.10 | devops1     |
| localhost    | mariadb.sys |
| localhost    | root        |
+--------------+-------------+
4 rows in set (0.004 sec)

This means If the container changed its IP, the site will be Internal Server Error.
Note: If sites exist the migration from old to new works well.

Have any idea to work with this ?

[revant]

there's is no patched bench any more.

official bench from pip install is used. so you need --no-mariadb-socket while creating new site

mentioned here https://github.com/revant/frappe_docker/blob/refactor-single-image/docs/migrate-from-multi-image-setup.md#configurator

@sdfateh

check this migration guide https://github.com/revant/frappe_docker/blob/refactor-single-image/docs/migrate-from-multi-image-setup.md

I test the new image and build my 4 custom apps. and I have approval from the testers now. also I tried v13 & v14 and it looks good.
Also, the migration for existing data is OK.

I think we can go ahead with the new single image ! 🥳
Let's say after 1 week. is that good or you?

[revant]

Sure we'll merge next week? Monday 16th

[revant]

PWD stopped working somehow. On PWD instance it only starts db and redis. Locally it starts all services. Following seems to be working locally.

docker swarm init
wget https://raw.githubusercontent.com/revant/frappe_docker/refactor-single-image/pwd.yml
docker stack deploy -c pwd.yml pwd

Edit:

fixed by adding volumes for logs and assets.

I am hitting this error while trying to build a custom image

[africlouds]

I can confirm that all the migration tests were successful for me

[sdfateh]

I can confirm this edit builds v13 and v14 with 4 custom apps successfully and fully functional with me ( and it solved some issues that appeared with the previous build ).

Also, the migration going successful for me for all data!

We can go with these edits,
but we have to keep the previous images for any reason of use later.

@revant You're the man. Thank you for simplifying this. Sorry I wasn't around to contribute took some time away over the holiday season. Single container looks great. I think what's super important for the project is newbies being able to join easily. I'll try deploying it and seeing how it runs.
