From 6ed33af0636e48d4bd9e834b6c9ab79233807aa4 Mon Sep 17 00:00:00 2001 From: Robert Drake Date: Sat, 6 Aug 2016 02:35:42 -0400 Subject: [PATCH 01/10] Changes to Dockerfile to make the build faster To download a new version with docker, I've been running git pull docker-compose build --no-cache This is slow, but no-cache is needed so that "git clone" pulls the latest copy. Most of the slowness comes from pulling down apt files each time a rebuild needs to be done. If we move that into a docker image then only the local changes need to be rebuilt. Further refinements could be done. If the python dependencies that are brought in from requirements.txt could be moved to an image then nothing would change between updates as long as dependant versions hadn't changed. This would probably be more trouble than it's worth, unless you're recreating netbox containers 10-20 times a day. --- Dockerfile | 26 ++++++-------------------- requirements.txt | 1 + 2 files changed, 7 insertions(+), 20 deletions(-) diff --git a/Dockerfile b/Dockerfile index c2e2c38ab34..aac301f2bd9 100644 --- a/Dockerfile +++ b/Dockerfile @@ -1,24 +1,10 @@ -FROM ubuntu:14.04 +FROM python:2.7-wheezy -RUN apt-get update && apt-get install -y \ - python2.7 \ - python-dev \ - git \ - python-pip \ - libxml2-dev \ - libxslt1-dev \ - libffi-dev \ - graphviz \ - libpq-dev \ - build-essential \ - gunicorn \ - --no-install-recommends \ - && rm -rf /var/lib/apt/lists/* \ - && mkdir -p /opt/netbox \ - && cd /opt/netbox \ - && git clone --depth 1 https://github.com/digitalocean/netbox.git -b master . \ - && pip install -r requirements.txt \ - && apt-get purge -y --auto-remove git build-essential +WORKDIR /opt/netbox + +ADD . /opt/netbox +#RUN git clone --depth 1 https://github.com/digitalocean/netbox.git -b master . \ +RUN pip install -r requirements.txt ADD docker/docker-entrypoint.sh /docker-entrypoint.sh ADD netbox/netbox/configuration.docker.py /opt/netbox/netbox/netbox/configuration.py diff --git a/requirements.txt b/requirements.txt index 40b0b707fea..f1836ea7f71 100644 --- a/requirements.txt +++ b/requirements.txt @@ -1,3 +1,4 @@ +gunicorn==17.5 cryptography==1.4 Django==1.10 django-debug-toolbar==1.4 From de8fd550cba5f8a28db9fd1927732ff1d144fdae Mon Sep 17 00:00:00 2001 From: Jeremy Stretch Date: Thu, 18 Aug 2016 10:12:43 -0400 Subject: [PATCH 02/10] Fixes #484: Allow bulk deletion of >1K objects --- netbox/netbox/settings.py | 3 +++ 1 file changed, 3 insertions(+) diff --git a/netbox/netbox/settings.py b/netbox/netbox/settings.py index 6e2359ebe6f..289367d37c4 100644 --- a/netbox/netbox/settings.py +++ b/netbox/netbox/settings.py @@ -164,6 +164,9 @@ STATICFILES_DIRS = ( os.path.join(BASE_DIR, "project-static"), ) +# Disable default limit of 1000 fields per request.

It was cloning the "master" branch, so trying to test a development change was difficult. I believe I've fixed it so that the "master" branch and "develop" branch can use the same Dockerfile options. You override which branch it pulls by setting a build-args variable, either via docker-compose or in the docker build options. --- Dockerfile | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/Dockerfile b/Dockerfile index fc05a45075c..2cf8b929464 100644 --- a/Dockerfile +++ b/Dockerfile @@ -2,9 +2,10 @@ FROM python:2.7-wheezy WORKDIR /opt/netbox -ADD . /opt/netbox -RUN git clone --depth 1 https://github.com/digitalocean/netbox.git -b master . \ -RUN pip install gunicorn==17.5 && pip install -r requirements.txt +ARG BRANCH=master +ARG URL=https://github.com/digitalocean/netbox.git +RUN git clone --depth 1 $URL -b $BRANCH . && \ + pip install gunicorn==17.5 && pip install -r requirements.txt ADD docker/docker-entrypoint.sh /docker-entrypoint.sh ADD netbox/netbox/configuration.docker.py /opt/netbox/netbox/netbox/configuration.py
