Docker microservice for LineageOS Continuous Integration and Continuous Deployment
A fair number of dependencies is needed to build LineageOS, plus a Linux system (and a discrete knowledge of it). With Docker we give you a minimal Linux build system with all the tools and scripts already integrated, easing considerably the creation of your own LineageOS build.
Moreover Docker runs also on Microsoft Windows and Mac OS, which means that LineageOS can be built on such platforms without requiring a dual boot system or a manual set up of a Virtual Machine.
The official Docker guides are well-written:
- Linux (Ubuntu, Debian, CentOS and Fedora are officially supported)
- Windows 10/Windows Server 2016 64bit
- Mac OS El Capitan 10.11 or newer
If your Windows or Mac system doesn't satisfy the requirements (or if you have Oracle VirtualBox installed, you can use Docker Toolbox. Docker Toolbox is not described in this guide, but it should be very similar to the standard Docker installation.
Once you can run the hello-world
image you're ready to
start!
This Docker image contains a great number of settings, to allow you to fully customize your LineageOS build. Here you can find all of them, with the default values between the brackets.
TL;DR - go to the Examples
The two fundamental settings are:
BRANCH_NAME (lineage-16.0)
: LineageOS branch, see the branch list here (multiple comma-separated branches can be specified)DEVICE_LIST
: comma-separated list of devices to build
Running a build with only these two set will create a ZIP file almost identical to the LineageOS official builds, just signed with the test keys.
When multiple branches are selected, use DEVICE_LIST_<BRANCH_NAME>
to specify
the list of devices for each specific branch (see the examples).
To include microG (or possibly the actual Google Mobile Services) in your build,
LineageOS expects certain Makefiles in vendor/partner_gms
and variable
WITH_GMS
set to true
. gms.mk is included by default. To use a specific
makefile in vendor/partner_gms/products
, set it with the GMS_MAKEFILE
varible, for example: gms_fdroid.mk
This repo contains the common packages included for
official lineageos4microg builds. To include it in your build, create an XML
(the name is irrelevant, as long as it ends with .xml
) in the
/home/user/manifests
folder with this content:
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project path="vendor/partner_gms" name="lineageos4microg/android_vendor_partner_gms" remote="github" revision="master" />
</manifest>
If you wish to add other apps to your ROM, you can include a repository with
source code or prebuilt APKs. For prebuilt apks, see the android_vendor_partner_gms
repository for examples on how the Android.mk
file should look like.
Include the repo with another manifest file like this:
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="your-github-user/your-repo" path="prebuilts/my-custom-apps" remote="github" revision="master" />
</manifest>
And when starting the build, set the CUSTOM_PACKAGES
variable to a list of app names
(defined by LOCAL_MODULE
in Android.mk
) separated by spaces.
There are two options for the signature spoofing patch required for microG:
- "Original" patches
- Restricted patches
With the "original" patch the FAKE_SIGNATURE permission can be granted to any user app: while it may seem handy, this is considered dangerous by a great number of people, as the user could accidentally give this permission to rogue apps.
A more strict option is the restricted patch, where the FAKE_SIGNATURE permission can be obtained only by privileged system apps, embedded in the ROM during the build process.
The signature spoofing patch can be optionally included with:
SIGNATURE_SPOOFING (no)
:yes
to use the original patch,restricted
for the restricted one,no
for none of them
If in doubt, use restricted
: note that packages that requires the
FAKE_SIGNATURE permission must be included in the build as system apps
(e.g. as part of GMS or CUSTOM_PACKAGES
)
Some proprietary files are needed to create a LineageOS build, but they're not included in the LineageOS repo for legal reasons. You can obtain these blobs in three ways:
- by pulling them from a running LineageOS
- by extracting them from a LineageOS ZIP
- by downloading them from TheMuppets GitHub and GitLab repositories (unofficial)
The third way is the easiest one and is enabled by default; if you're OK with
that just move on, otherwise set INCLUDE_PROPRIETARY (true)
to false
and
manually provide the blobs (not explained in this guide).
To enable OTA for you builds, you need to run a server that speaks the protocol
understood by the LineageOS updater app and provide the URL to this
server as OTA_URL
variable for the build.
One implementation is LineageOTA, which is also available as Docker image. Follow these steps to prepare your builds for OTA:
- Run the Docker image
julianxhokaxhiu/lineageota
- Port 80 exposed to the internet (might want to add an HTTPS reverse proxy)
- The
/srv/zips
directory/volume of the CICD image mounted at/var/www/html/builds/full
(can be read-only)
- Set environment variables when building
ZIP_SUBDIR
tofalse
OTA_URL
to the address of the OTA server, with/api
appended
If you don't setup a OTA server you won't be able to update the device from the updater app (but you can still update it manually with the recovery of course).
By default, builds are signed with the Android test keys. If you want to sign your builds with your own keys (highly recommended):
SIGN_BUILDS (false)
: set totrue
to sign the builds with the keys contained in/srv/keys
; if no keys are present, a new set will be generated
Other useful settings are:
CCACHE_SIZE (50G)
: change this if you want to give more (or less) space to ccacheWITH_SU (false)
: set totrue
to embedsu
in the build (note that, even when set tofalse
, you can still enable root by flashing the su installable ZIP). This is only for lineage version 16 and below.RELEASE_TYPE (UNOFFICIAL)
: change the release type of your buildsBUILD_TYPE (userdebug)
: type of your builds, see Android docsBUILD_OVERLAY (false)
: normally each build is done on the source tree, then the tree is cleaned withmka clean
. If you want to be sure that each build is isolated from the others, setBUILD_OVERLAY
totrue
(longer build time). Requires--cap-add=SYS_ADMIN
.LOCAL_MIRROR (false)
: change this totrue
if you want to create a local mirror of the LineageOS source (> 200 GB)CRONTAB_TIME (now)
: instead of building immediately and exit, build at the specified time (uses standard cron format)ZIP_SUBDIR (true)
: Move the resulting zips to $ZIP_DIR/$codename instead of $ZIP_DIR/PARALLEL_JOBS
: Limit the number of parallel jobs to run (-j
forrepo sync
andmka
). By default, the build system should match the number of parallel jobs to the number of cpu cores on your machine. Reducing this number can help keeping it responsive for other tasks.REPO_INIT (https://github.com/LineageOS/android)
: Change the default android sourceHEROLTE_PICKS (false)
: Apply 8890q LOS picks. None by default on lineage-20MANIFESTS_8890 (false)
: Use local manifests for Samsung 8890 on lineage-20
The full list of settings, including the less interesting ones not mentioned in this guide, can be found in the Dockerfile.
You also have to provide Docker some volumes, where it'll store the source, the resulting builds, the cache and so on. The volumes are:
/srv/src
, for the LineageOS sources/srv/zips
, for the output builds/srv/logs
, for the output logs/srv/ccache
, for the ccache/srv/local_manifests
, for custom manifests (optional)/srv/userscripts
, for the user scripts (optional)
When SIGN_BUILDS
is true
/srv/keys
, for the signing keys
When BUILD_OVERLAY
is true
/srv/tmp
, for temporary files
When LOCAL_MIRROR
is true
:
/srv/mirror
, for the LineageOS mirror

lineageos4microg/docker-lineage-cicd
If there are already keys in /home/user/keys
they will be used, otherwise a
new set will be generated before starting the build (and will be used for every
subsequent build).
The microG and FDroid packages are not present in the LineageOS repositories, and must be provided e.g. through android_vendor_partner_gms.
Build for four devices on lineage-17.1 and lineage-18.1 (officially supported), custom keys, restricted signature spoofing with integrated microG and FDroid, custom OTA server

Build for a6000 (not officially supported), custom keys, restricted signature spoofing with integrated microG and FDroid
As there is no official support for this device, we first have to include the
sources in the source tree through an XML in the /home/user/manifests
folder;
from this thread we get the links of:
- Device tree: https://github.com/dev-harsh1998/android_device_lenovo_a6000
- Common Tree: https://github.com/dev-harsh1998/android_device_lenovo_msm8916-common
- Kernel: https://github.com/dev-harsh1998/kernel_lenovo_msm8916
- Vendor blobs: https://github.com/dev-harsh1998/proprietary-vendor_lenovo
Then, with the help of lineage.dependencies from the
device tree and the
common tree we create an XML
/home/user/manifests/a6000.xml
with this content:
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="dev-harsh1998/android_device_lenovo_a6000" path="device/lenovo/a6000" remote="github" />
<project name="dev-harsh1998/android_device_lenovo_msm8916-common" path="device/lenovo/msm8916-common" remote="github" />
<project name="dev-harsh1998/kernel_lenovo_msm8916" path="kernel/lenovo/a6000" remote="github" />
<project name="dev-harsh1998/proprietary-vendor_lenovo" path="vendor/lenovo" remote="github" />
<project name="LineageOS/android_device_qcom_common" path="device/qcom/common" remote="github" />
</manifest>
We also want to include microG so, like before, create an XML (for
example /home/user/manifests/microg.xml
) with this content:
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project path="vendor/partner_gms" name="lineageos4microg/android_vendor_partner_gms" remote="github" revision="master" />
</manifest>
We also set INCLUDE_PROPRIETARY=false
, as the proprietary blobs are already
provided by the repo
https://github.com/dev-harsh1998/prorietary_vendor_lenovo (so we
don't have to include the TheMuppets repo).
Now we can just run the build like it was officially supported:
docker run \
-e "BRANCH_NAME=lineage-15.1" \
-e "DEVICE_LIST=a6000" \
-e "SIGN_BUILDS=true" \
-e "SIGNATURE_SPOOFING=restricted" \
-e "WITH_GMS=true" \
-e "INCLUDE_PROPRIETARY=false" \
-v "/home/user/lineage:/srv/src" \
-v "/home/user/zips:/srv/zips" \
-v "/home/user/logs:/srv/logs" \
-v "/home/user/cache:/srv/ccache" \
-v "/home/user/keys:/srv/keys" \
-v "/home/user/manifests:/srv/local_manifests" \
