\nHere is how I install the latest Docker version on Oracle Linux 7. You find several blog posts about it which all install ‘docker-engine’. But things move fast in this agile world and docker package name has changed. The Community Edition is now ‘docker-ce’ and you want this one to run the latest version.
\n
\nI’m on OEL 7.4 but should also wotj on RHEL 7:<\/p>\n
[root@VM188 yum]# cat \/etc\/oracle-release\nOracle Linux Server release 7.4<\/code><\/pre>\ndocker-engine<\/h3>\n
If you enable [ol7_addons] you can install ‘docker-engine:’<\/p>\n
\n# yum-config-manager --enable ol7_addons\n# yum info docker-engine\nLoaded plugins: ulninfo\nAvailable Packages\nName : docker-engine\nArch : x86_64\nVersion : 17.06.2.ol\nRelease : 1.0.1.el7\nSize : 21 M\nRepo : ol7_addons\/x86_64\nSummary : The open-source application container engine\nURL : https:\/\/dockerproject.org\nLicense : ASL 2.0\nDescription : Docker is an open source project to build, ship and run any application as a\n : lightweight container.\n<\/code><\/pre>\nBut forget it. That’s 17.06 which is 6 months old. You should consider Docker as a puppy. 6 month in puppy’s years is like 3 human years. So many changes happened.<\/p>\n
You can remove all those old things:<\/p>\n
\n# yum remove docker docker-common docker-selinux docker-engine\n<\/code><\/pre>\ndocker-ce<\/h3>\n
I’ve not found ‘docker-ce’ on OL7 repositories, as only the Enterprise Edition is there. Then I added the CentOS repo (with yum-config-manager that you can get with yum-utils if you don’t have it already):<\/p>\n
\nyum -y install yum-utils \nyum-config-manager --add-repo https:\/\/download.docker.com\/linux\/centos\/docker-ce.repo\n<\/code><\/pre>\nOnce done, I’ve just installed Docker Community Edition with:<\/p>\n
\nyum -y install docker-ce\n<\/code><\/pre>\nAnd, at that time I got the version 17.12 easily:<\/p>\n
\n[root@VM188 ~]# yum info docker-ce\nLoaded plugins: ulninfo\nInstalled Packages\nName : docker-ce\nArch : x86_64\nVersion : 17.12.0.ce\nRelease : 1.el7.centos\nSize : 123 M\nRepo : installed\nFrom repo : docker-ce-stable\nSummary : The open-source application container engine\nURL : https:\/\/www.docker.com\nLicense : ASL 2.0\nDescription : Docker is an open source project to build, ship and run any application as a\n : lightweight container.\n...\n<\/code><\/pre>\nBut now there’s a new version available:<\/p>\n
\nAvailable Packages\nName : docker-ce\nArch : x86_64\nVersion : 18.03.0.ce\nRelease : 1.el7.centos\nSize : 35 M\nRepo : docker-ce-stable\/x86_64\nSummary : The open-source application container engine\nURL : https:\/\/www.docker.com\nLicense : ASL 2.0\nDescription : Docker is an open source project to build, ship and run any application as a\n : lightweight container.\n<\/code><\/pre>\nThe problem is that if you want to install docker-ce in this latest version, you will now get:<\/p>\n
\nResolving Dependencies\n--> Running transaction check\n---> Package docker-ce.x86_64 0:18.03.0.ce-1.el7.centos will be installed\n--> Processing Dependency: pigz for package: docker-ce-18.03.0.ce-1.el7.centos.x86_64\n--> Finished Dependency Resolution\nError: Package: docker-ce-18.03.0.ce-1.el7.centos.x86_64 (docker-ce-stable)\n Requires: pigz\n You could try using --skip-broken to work around the problem\n** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows:\n2:microcode_ctl-2.1-22.5.0.3.el7_4.x86_64 has missing requires of kernel\n<\/code><\/pre>\n(Ok Google, this is what you need to index…)<\/p>\n
pigz<\/h3>\n
Starting from version 18.02 there’s a new dependency on ‘pigz’ for parallel gzip.<\/p>\n
To get this ‘pigz’ package from the OL7 repository you need to enable EPEL in \/etc\/yum.repos.d\/public-yum-ol7.repo<\/p>\n

yum-config-manager --enable ol7_developer_EPEL<\/code><\/pre>\nNow, I’m able to install the latest docker-ce:<\/p>\n

You may wonder why I install Docker on Oracle Linux rather than CentOS. The MOS Doc ID 2216342.1<\/a> mentions that Oracle will support customers running Oracle Database (single instance) in Docker containers running on Oracle Linux 7 with UEK4 or Red Hat Enterprise Linux 7<\/i>.<\/p>\nIf you want to validate your Docker install for running Oracle Database, the easiest is to use the image build script provided by Oracle:<\/p>\n
\ngit clone https:\/\/github.com\/oracle\/docker-images.git\ncd .\/docker-images\/OracleDatabase\/SingleInstance\/dockerfiles\/\n# download and move linuxx64_12201_database.zip is in 12.2.0.1 subdirectory\nsh buildDockerImage.sh -v 12.2.0.1 -e\n<\/code><\/pre>\n
