Docker Tooling in Eclipse Ask anybody these days about hot software technology topics and youre bound to hear the word Containers which are light weight virtual machines that operate on the process level. They can be instantiated very quickly and are easy to configure. If you are going to enter the world of Containers, then you will undoubtedly run into the name Docker which is quickly becoming the ubiquitous standard. Docker is the trademarked company name but also used when referring to their implementation of container technology. Introduction. Some brief terminology is in order. An Image is a template for creating a Container. A Container is an instance of an Image with some process or application to run along with an environment specification. There are a large assortment of pre formed Docker Images out there for various Operating Systems e. Fedora, Ubuntu, Solaris. Get FedoraValgrind fatal error, running on Slitaz.

When a program is run under Valgrinds supervision, all reads and writes of memory are checked, and calls to mallocnewfreedelete are. You can take an existing Image, modify it, and save that as a new Image to use later. For example, you might take a base Fedora 2. Image, install ssh on it, and then store that as a new Image to use whenever you need to run an application that uses ssh in a Container. Images are stored in a registry and have an identifying id which includes a repository and a tag. For example fedora 2. Fedora 2. 2 OS from the fedora repository. To use an Image locally, it first needs to be pulled from a registry. To share it with others, it is pushed to a registry. There is a default Docker registry known as Docker Hub where you can find base OS Images. These base OS Images are available to all. If you wish to modify these Images, or create your own, you need to sign up for a personal Docker Hub account and store Images under a personal repository. A personal repository is specified by prefixing the repository with your username in the Image id for example, jjohnstnfedora 2. These Images in turn can be shared with others, modified, etc You may also create a private registry, if desired. In such a case, the registry name needs to be specified as part of the Image id registryrepository tag means you are not using the default Docker Hub registry. Modifying an existing Image can be done two ways. The first way is to use a special file called a Dockerfile which contains instructions on which Image to base upon and what modifications are desired e. The other way to modify an Image is to create a Container that runs a shell and then perform actions in the Container such as installing packages, configuration, etc Once all modifications are made, commit the Container as a new Image. To use Docker, you must first start a Docker daemon. The Docker daemon knows about Docker Hub and is used to manage the set of local Docker Images and Containers. The daemon can be set up to start up as a system service Linux or can be started manually using the docker command note that lower case docker is used when referring to the command. The docker command is also used for performing various tasks for Docker Images and Containers as well as registry support. On some systems such as Windows, the Docker daemon cannot be started locally. In these instances, one can use Docker Machine which starts the Docker daemon in a VM Virtual Machine for you, provides the Host with any certificates required to connect with the Docker daemon, and exports environment variables that contain all the information needed to communicate with it e. TCP address. Formerly, one would use Boot. Docker to do all of this, but this has been deprecated. The Docker Tooling Project Starting in the fall of 2. Eclipse Linux Tools Project at Red Hat Inc Jeff Johnston, Roland Grunberg, and Xavier Coulon developed plug ins to allow management of Docker Images and Containers within Eclipse to mimic some of the functionality provided by the docker command and enhance its functionality through a robust UI. To communicate with the Docker daemon, a Java API library was used. At the time, there were two such public Java API Libraries available docker java and docker client, but only docker client from Spotify had Unix socket support which is the default configuration for the Docker daemon on Linux. Although the Docker daemon also supports setting up TCP sockets, this would have required the end user being forced to add a special option on the daemon start up and this was deemed too cumbersome. It should be noted that the other Java API Library at the time docker java has since added Unix socket support. While docker client had Unix socket support, it had implemented this using a  package with little support unix socket factory, that made use of the socket functionality from another poorly supported package, junix socket. A patch to convert docker client to use JNR Unix sockets was submitted to github and this was accepted upstream. The Linux Tools Docker Tooling plug ins were successfully shipped as part of the Linux Tools 4. Eclipse Mars in June2. Linux Tools 4. 1 which was shipped as part of the Eclipse Mars. Sept2. 01. 5. Getting Started. If running on Linux, install the appropriate Docker package on your system. If running on Windows, you can use Docker Machine to start a virtual machine running the Docker daemon. On Eclipse install the Mars. Eclipse and then install the Docker Tooling feature which can be installed from the default Mars update site Help Install New Software. Before starting Eclipse, ensure  the Docker daemon is running. When you start Eclipse, you will see a new perspective has been added, called Docker Tooling. Switch to this perspective. It consists of three new views Docker Explorer, Docker Images, and Docker Containers along with the standard Eclipse Console and Properties views. The first time you start your workspace, there will be no Connection to a Docker daemon, so you should see the following Clicking on the message found in the Docker Explorer View will bring up the New Connection Wizard The New Connection Wizard upon opening will attempt to fill in defaults on behalf of the end user. On a Linux system, the wizard looks for varrundocker. Otherwise, the wizard will look for the environment variables DOCKERHOST, DOCKERTLSVERIFY, and DOCKERCERTPATH to initialize default TCP settings. The wizard will present a default name but you may rename the connection as desired. The Search button can be used to find a local running Docker Machine instance andor you can test the connection using the Test Connection button to ensure that the daemon is running and responding correctly. A new connection can be created any time from the Docker Explorer View toolbar. Once a connection is created, it becomes the default active connection. This results in the following To change the active connection, simply click on any of the nodes in the Docker Explorer View. The Docker Image, and Docker Container views will display content based on the selected connection. These lists are also available in the Docker Explorer tree view by expanding a connection node and clicking on either Images or Containers. By default, the lists of Images and Containers are filtered. Untagged and intermediate Images as well as stopped Containers are not shown. These settings may be changed from the Docker Explorer Views Customize view pull down menu. Pulling Images. The next step is to ensure you have some Images to run. When you first start the Docker daemon, there will be no Images. Images need to be pulled from a registry.
