From: Peter Mikus Date: Fri, 19 May 2017 07:42:39 +0000 (+0200) Subject: CSIT-607 Optimize VIRL job scheduling algorithm X-Git-Url: https://gerrit.fd.io/r/gitweb?p=csit.git;a=commitdiff_plain;h=e2f9bdd098fb0008cc4fc2f8c8298ebe0d6ef062;hp=9339a16712a48e85fe97d3e6d9c3ab4a61455d1b CSIT-607 Optimize VIRL job scheduling algorithm Optimize VIRL job scheduling algorithm based on available VIRL host capacity. Add IP pool availability pre-checks. - add quota based on max. allowe IPs and max. allowe VMs per virl - use one common bootstrap file instead of two separate files (one for ubutnut, another for centos) Change-Id: Ic40122a084624ff9c5eafa9f372b0451e857e29a Signed-off-by: Peter Mikus --- diff --git a/bootstrap-centos.sh b/bootstrap-centos.sh deleted file mode 100755 index b7c6891ef6..0000000000 --- a/bootstrap-centos.sh +++ /dev/null @@ -1,384 +0,0 @@ -#!/bin/bash -# Copyright (c) 2016 Cisco and/or its affiliates. -# Licensed under the Apache License, Version 2.0 (the "License"); -# you may not use this file except in compliance with the License. -# You may obtain a copy of the License at: -# -# http://www.apache.org/licenses/LICENSE-2.0 -# -# Unless required by applicable law or agreed to in writing, software -# distributed under the License is distributed on an "AS IS" BASIS, -# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. -# See the License for the specific language governing permissions and -# limitations under the License. - -set -x - -cat /etc/hostname -cat /etc/hosts - -sudo yum install -y python-devel python-virtualenv - -VIRL_SERVERS=("10.30.51.28" "10.30.51.29" "10.30.51.30") - -VIRL_USERNAME=jenkins-in -VIRL_PKEY=priv_key -VIRL_SERVER_STATUS_FILE="status" -VIRL_SERVER_EXPECTED_STATUS="PRODUCTION" - -SCRIPT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )" - -VIRL_TOPOLOGY=$(cat ${SCRIPT_DIR}/VIRL_TOPOLOGY_CENTOS) -VIRL_RELEASE=$(cat ${SCRIPT_DIR}/VIRL_RELEASE_CENTOS) - -SSH_OPTIONS="-i ${VIRL_PKEY} -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o BatchMode=yes -o LogLevel=error" - -TEST_GROUPS=("gre,ipv6,lisp,policer,rpf,softwire" "dhcp,ipsec,l2bd,l2xc,telemetry,vrf,vxlan" "cop,fds,honeycomb,iacl,ipv4,tap,vhost,vlan") -SUITE_PATH="tests.func" -SKIP_PATCH="SKIP_PATCH" - -# Create tmp dir -mkdir ${SCRIPT_DIR}/tmp - -# Use tmp dir to store log files -LOG_PATH="${SCRIPT_DIR}/tmp" - -# Use tmp dir for tarballs -export TMPDIR="${SCRIPT_DIR}/tmp" - -SHARED_MEMORY_PATH="/dev/shm" - -function ssh_do() { - echo - echo "### " ssh $@ - ssh ${SSH_OPTIONS} $@ -} - -rm -f ${VIRL_PKEY} -cat > ${VIRL_PKEY} <&1) - echo VIRL HOST $virl_server_candidate status is \"$virl_server_status\" - if [ "$virl_server_status" == "$VIRL_SERVER_EXPECTED_STATUS" ] - then - # Candidate is in good status.
