+
+* Important notice
+
+As the current docker install of gogocarto as of <2020-10-20 Tue> is
+far from being mature, we try here to get only the released part.
+
+We are talking of: 
+[[https://gitlab.adullact.net/pixelhumain/GoGoCarto/-/blob/f3c10f16fc08b533ef44f1325fdb50f87fa73224/docs/installation_docker.md][gogocarto docker install documentation]]
+
+** Intermediate docker image is cached on docker.0k.io if needed
+
+To rebuild a new version, I pushed the huge docker image of
+=gogocarto= container that is required in the process (that contains
+apache and all build/install tools). Note that this should not require
+to be rebuild if anything important changes in the directory =docker/=.
+
+Using:
+
+#+begin_src sh
+docker_tree_hash=$(git rev-parse HEAD:docker)
+docker tag docker_gogocarto docker.0k.io/gogocarto-builder:${docker_tree_hash}
+docker push docker.0k.io/gogocarto-builder:${docker_tree_hash}
+#+end_src
+
+So, if needed, it can be pulled back to avoid the hassle of making it:
+
+#+begin_src sh
+docker_tree_hash=$(git rev-parse HEAD:docker)
+docker pull docker.0k.io/gogocarto-builder:${docker_tree_hash} &&
+docker tag docker.0k.io/gogocarto-builder:${docker_tree_hash} docker_gogocarto
+#+end_src
+
+You still need to do (as of <2020-10-20 Tue>):
+- get the latest source code
+- =make up= to launch de containers with the images
+- =make shell= from the latest git repos
+- =make init= in the container
+
+** Full release is cached on =docker.0k.io/downloads=
+
+This is the content of the source tree, once populated by =make init=.
+
+*** mongodb is not included
+
+As of <2020-10-23 Fri>, the =Makefile='s =init= target is:
+
+#+begin_src sh
+$ grep ^init Makefile -A1
+init: install assets load-fixtures fix-perms ## Initialize the project
+
+#+end_src
+
+Note that ``load-fixtures`` target is actually mongodb initialization:
+
+#+begin_src sh
+load-fixtures: ## Create the DB schema, generate DB classes and load fixtures
+        $(SYMFONY) doctrine:mongodb:schema:create
+        $(SYMFONY) doctrine:mongodb:generate:hydrators
+        $(SYMFONY) doctrine:mongodb:generate:proxies
+        $(SYMFONY) doctrine:mongodb:fixtures:load -n
+#+end_src
+
+This will be done in the =hooks/mongo_database-relation-joined= accordingly.
+
+
+*** o create the full data release bundle this is what was made:
+
+#+begin_src sh
+## correct bundles links (no idea if it is needed)
+(
+  cd web/bundles
+  for i in *; do
+      link_target=$(readlink "$i")
+      ln -sf /opt/apps/gogocarto"${link_target#/var/www}" "$i"
+  done
+)
+## Force original versions
+git co web/index.php config/packages/doctrine_mongodb.yaml bin/console
+sed -ri "s/^(<\?php)/\1\n\ini_set('memory.limit', '1024M');/" \
+    web/index.php bin/console
+sed -ri "s%dirname\(__DIR__\)\.'%'/opt/apps/gogocarto%g" \
+    web/index.php
+commit_sha=$(git describe HEAD --tags)
+tar cjv \
+    bin web vendor config src templates translations \
+    --exclude=.git --exclude=.gitignore \
+    > gogocarto-${commit_sha}.tar.bz2
+#+end_src
+
+This is still far from being perfect, I wonder if we can just remove
+all non '\*.{php,yml,js}' files. I noticed many many unrelated files in
+=vendor/=.
+
+We need =bin= for symphony utilities that allows to setup things.
+
+* Roadmap
+
+** TODO mongo / the default database name is probably not correctly set.
+
+Indeed, it seems it is defaulted to =gogocarto_default= and I didn't find
+yet how to set it. There's a connection with SAAS mode I think.
