From: Alexandru Avadanii Date: Thu, 24 Nov 2016 23:02:04 +0100 Subject: [PATCH] CI: deploy-cache: Store and reuse deploy artifacts Add support for caching deploy artifacts, like bootstraps and target images, which take a lot of time at each deploy to be built, considering it requires a cross-debootstrap via qemu-user-static and binfmt. For OPNFV CI, the cache will piggy back on the mechanism, and be located at: /iso_mount/opnfv_ci//deploy-cache TODO: Use dea interface adapter in target images fingerprinting. TODO: remote fingerprinting TODO: differentiate between bootstraps and targetimages, so we don't end up trying to use one cache artifact type as the other. TODO: implement sanity checks for bootstrap and target images; TODO: switch `exec_cmd('mkdir ...')` to `create_dir_if_not_exists`; JIRA: ARMBAND-172 Signed-off-by: Alexandru Avadanii --- ...p_admin_node.sh-deploy_cache-install-hook.patch | 73 +++++ ci/deploy.sh | 14 +- deploy/cloud/configure_settings.py | 4 + deploy/cloud/deployment.py | 12 + deploy/deploy.py | 25 +- deploy/deploy_cache.py | 312 +++++++++++++++++++++ deploy/deploy_env.py | 13 +- deploy/install_fuel_master.py | 9 +- 8 files changed, 453 insertions(+), 9 deletions(-) create mode 100644 build/f_repos/patch/fuel-main/0006-bootstrap_admin_node.sh-deploy_cache-install-hook.patch create mode 100644 deploy/deploy_cache.py diff --git a/build/f_repos/patch/fuel-main/0006-bootstrap_admin_node.sh-deploy_cache-install-hook.patch b/build/f_repos/patch/fuel-main/0006-bootstrap_admin_node.sh-deploy_cache-install-hook.patch new file mode 100644 index 0000000..69a4c22 --- /dev/null +++ b/build/f_repos/patch/fuel-main/0006-bootstrap_admin_node.sh-deploy_cache-install-hook.patch @@ -0,0 +1,73 @@ +From: Alexandru Avadanii +Date: Mon, 28 Nov 2016 14:27:48 +0100 +Subject: [PATCH] bootstrap_admin_node.sh: deploy_cache install hook + +Tooling on the automatic deploy side was updated to support deploy +caching of artifacts like bootstrap (and id_rsa keypair), target +images etc. + +Add installation hook that calls `fuel-bootstrap import` instead of +`build` when a bootstrap tar is available in the agreed location, +/var/lib/opnfv/cache/bootstraps/. + +JIRA: ARMBAND-172 + +Signed-off-by: Alexandru Avadanii +--- + iso/bootstrap_admin_node.sh | 20 +++++++++++++++++++- + 1 file changed, 19 insertions(+), 1 deletion(-) + +diff --git a/iso/bootstrap_admin_node.sh b/iso/bootstrap_admin_node.sh +index abc5ffb..15e6261 100755 +--- a/iso/bootstrap_admin_node.sh ++++ b/iso/bootstrap_admin_node.sh +@@ -61,6 +61,8 @@ wget \ + ASTUTE_YAML='/etc/fuel/astute.yaml' + BOOTSTRAP_NODE_CONFIG="/etc/fuel/bootstrap_admin_node.conf" + CUSTOM_REPOS="/root/default_deb_repos.yaml" ++OPNFV_CACHE_PATH="/var/cache/opnfv/bootstraps" ++OPNFV_CACHE_TAR="opnfv-bootstraps-cache.tar" + bs_build_log='/var/log/fuel-bootstrap-image-build.log' + bs_status=0 + # Backup network configs to this folder.
