Axxana Blog Creating an Oracle Linux ASM Docker Image over Ubuntu 14.04

Prerequisites 64-bit Ubuntu 14.04 server General Information In this setup we are: Installing Docker Creating a non-root user with Sudo and Docker privileges (axxana) ASM device is /dev/sdb1. Enabling SQLNET and SSH to the container The default ASM port is 1521. The SSH port is 2222. The password for root and grid OS users in the container is axxana. The password for sys ASM user is axxana. The grid software is 12.2 without any patches. The container operating system is Oracle Linux 7.5. Within the container, there is no use of UDEV / ASMLIB or ASMFD: asm_diskstring='/dev/asm*','/bbx/data/*','/dev/*' All tests are done on regular Ubuntu 14.04 and on Axxana's ISO (based on 14.04). There is a crontab job to keep 15 days of trace files and remove audit files. Apply UDEV rules to make sure the device has permissions of the same container IDs: vi /etc/udev/rules.d/100-asm.rules KERNEL=="sdb1", NAME="ASM_DISK", OWNER="54421″, GROUP="54421″, MODE="0660″ udevadm trigger -sysname-match=sdb1 -verbose Verify the device has ASM labels: DISK_GROUP=$( blkid | grep oracleasm | sed 's/.*LABEL=\"\([^\"]*\)\" TYPE=\"oracleasm\"/\1/') if [ -z "$DISK_GROUP" ] then echo "device /dev/sdb1 has not asm metadata" else echo "device /dev/sdb1 has diskgroup $DISK_GROUP" fi Install Docker On Black Box as root: curl -fsSL https://get.docker.com/ | sh or: curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" apt-get update apt-cache policy docker-ce apt-get install -y docker-ce service docker status Add Users On Black Box as root: Add equivalent user IDs to the docker to follow (will be identified from outside): groupadd -g 54422 asmadmin useradd -u 54421 -g 54422 grid Add a dedicated user to manage the docker: adduser axxana -g 54422 echo "axxana:axxana" | chpasswd usermod -aG docker axxana usermod -aG sudo axxana sed -i '/PasswordAuthentication/d' /etc/ssh/sshd_config ; echo "PasswordAuthentication no" >> /etc/ssh/sshd_config sed -i '/PubkeyAuthentication/d' /etc/ssh/sshd_config ; echo "PubkeyAuthentication yes" >> /etc/ssh/sshd_config sed -i '/ChallengeResponseAuthentication/d' /etc/ssh/sshd_config ; echo "ChallengeResponseAuthentication no" >> /etc/ssh/sshd_config service ssh reload Build a New Image If you already have an image file, skip to the section below, titled Load Image. In this step, we will create a new image from scratch, and then pack it at the end. Ensure you have the following file: \\nas\shared\oracle_tools\DockerASM\docker_asm_build_scripts.tar.gz You can run /depo/build.sh + /depo/export.sh or you can run the following manual steps: Prepare the Files On Black Box as root: scp docker_asm_build_scripts.tar.gz /tmp mkdir /depo/ chown -R root:54422 /depo/ chmod 775 /depo tar xvfz -same-owner /tmp/docker_asm_build_scripts.tar.gz -C /depo/ rm -f /tmp/docker_asm_build_scripts.tar.gz List of the files Script Description adrci_script.sh Runs for crontab to delete trace files periodically build.sh Builds a docker image clean.sh Cleans all docker containers and an image crontab.setup A crontab job script for grid users; deletes trace files periodically disks.sql An SQL script for listing disks docker_descendants.py Checks docker images dependencies docker_folder/Dockerfile Builds instruction for docker image export.sh Exports a docker image and compresses it glogin.sql Establishes settings for proper formatting of SQL*Plus output grants.sql Grants database permission during the build process init+ASM.ora The initialization file for ASM instance install_grid.sh Installs script for grid linuxx64_12201_grid_home.zip Oracle 12.2 grid software (no patches) listener.ora Listener file oracle_asm Logrotate for Oracle logfiles rlwrap-0.42-1.el7.x86_64.rpm Handy tool to enable history in SQL*Plus, asmcmd run.sh Starts a container status.sh Provides images and container status Run the Build Image On Black Box as root/axxana: cd /depo/docker_folder docker build -t ynixon/docker_grid_asm .
